It doesn't even need to be free.  Larger sims would help this a ton. 
Other than a whole lot of code cleanup to yank out assumptions, there's 
no reason we couldn't have 1024x1024 sims, or whatever, with the same 
limits as a 256 sim has now.

Openspaces almost help here, but the steep 100% increase on price/prim 
is hard for people to swallow (you only get 7500 prims for all 4 regions).
