Hi y'all !!!
Nice to see our favorite forum reincarnated!!!

See: Description of the Hall Weather Machine / HWM -- http://www.foresight.org/nanodot/?p=2922
it would turn the Earth into combination of a giant: solar powered laser, telescope, image projector... The illumination / climate will be controllable with arbitrary areal resolution ( in "pixels" of say 1x1 km ). Season, hemishere, latitude-longitude ... becomes immaterial.
<<< Such Weather Machine using really huge bubbles ( 100s to 1000s KILOmeters wide ) positioned as levitated statites around the Sun will harness every available Watt from there ... Go to http://nextbigfuture.com/ and search for "hall weather machine" for looooots of details and comments. >>>
Back to planets: Make the bubbles self-replicating ( the construction materials are the air itself, the energy comes from the Sun ). The Seed machinery can be as little as grams or less, which could be easily spread with nearly light speeds accross the Galaxy using almost existing tech. The bubbly layer having also magnetic field generating capabilities, can create as powerful as necesary plasma window or other atmospheric retention system.
"Infect" Mars. Sending a kilo there nowadays costs under $100k. Wait several years. ...

...orrr:
"infect" Pluto. On, say, normal at it surface gravity 1 Bar troposphere height. 100ish km. Over the HWM cloud layer the atmosphere will be kept deeply cold in order the dissipation to be prevented: 280-300K on surface, 200K at the HWM altitude, 20-30K over it.
The Pluto surface illuminance is between 150 and 450 lux i.e. the same number of full tropical overhead moons on Earth, or dozens of times more intense than decent indoor light - between a cloudy day and sunrise/sunset in clear day on Earth, much more than enough to see colours and / or read ... . The photosynthesis minimum is 500-1000 lux for non-modified plants ( it is easy to imagine plants with lenses / mirrors concentrating light onto their photosynthetic organs with very very munimum mass punishment, making the optimal 3000-5000 lux for them locally! ).

The Josh Hall's Weather Machine covering Pluto shall provide almost complete greenhousing, not letting IR photons to escape until it is reached good healthy average around Zero celsius ( 270-280K ) all over the surface. Do not forget that the WM allows not only full phase, frequency, etc. but also directional control over the incident light, which means that "oases" comprising much of the planetary territory ( 1/2nd? , 2/3rds? 100%? ) to be formed regardless which side of the body is facing the Sun at any given moment. The botanical species introduced there could also, except optimizing locally the light flux for them, also providing landscape "fur" / "foam" covering the ground in order to keep it solid and stable underneath while on top the temperature is almost constant 300ish Kelvin ( climate like in Miami, Singapore, Brasilia... ).
THUS, Pluto and it numerous brethren in the Kuipert Belt could be terraformed WITHOUT using concentrating optics, stelar laser of different type, mass-streams, artificial fusion suns ...
The N2/02 atmosphere, separation plastic and biomass blankets for keeping the interior frozen ... could be produced brute force by utilizing nearly 100% of the available light / energy for period of several years / decades through processors which to extract the necessary elements from the frosty crust.

Pluto - balmy, murky... with thick warm troposphere at 8% of the Earth's surface gravity...

Hmmm, appealing, but... what if we don't get self-replication at those masses?
I'd love to see those places paraterraformed, using some sort of hybrid worldhouse system.
Use what is abundant and build to last

What better Hybrid Worldhouse System than HWM?!
Self-replicaton would be very simple - it is almost within our present day SciTech grasp.
Note: Self-replication = evolution and betterment, too.
Remember the http://en.wikipedia.org/wiki/Macrolife concept. It is self-replicating ecosystems/environments as meta-thesis to just self-replicating organisms.
Link this with the last discoveries about impact-ejecta interstellar panspermia's maths.
A Galaxy macrolifed via HWM-like systems infection in less than 1 000 000 years...
With "over 100 000 planetary mass objects per star" ... what? - 1 000 000 000 000 000 000 habitable worlds in the Milky way alone?!
