uh... what? Dollhouse is about "a group of men and women who can be imprinted with personality packages, including memories, skills, language—even muscle memory—for different assignments. When not imprinted with a personality package, they are mind-wiped, living like children in a futuristic dorm/lab dubbed the Dollhouse, with no memory of their assignments—or of much else."

How is that similar to this at all?

This actually sounds good - it would definitely be cool to see them reach the solar system 10 years from the pilot, then spend like five years there, or they could just cut it off when they get there.
This could easily go wrong though - using too much special effects, most of which look fake, and the stories - if it centers around the virtual stories I don't think it'll be interesting... and it probably will since the title is Virtuality... and if they don't face problems getting to the solar system this could be just pointless. It totally depends on the writing, acting, and special effects (but then again, what show doesn't?)...
Never watched Battlestar Galactica, so I don't know if they're similar or what not... but this show sounds original (the going to discover a new solar system)

the show sound good, sure is taken by star trek but the twist is good. I mean realizing that ye spend ye whole life in a virtual world, not knowing that it all fake.
