NThusim+ will handle the warp to match a curved projection surface. 
However, Sol7 will do that AND warp to a spherical surface as well.  At 
lesat that's my understanding.  Wayne has studied this far more than I 
have.

The TH2G gives me maximum flexibility with the system.  When I was using 
three 1024x768 projectors with both Need for Speed: Shift and FSX, I was 
getting good frame rates with no stuttering.  Then again, I'm using an 
Intel i7 960 with essentially 8 cores on board. :)
