Has anyone used the new Lightning for B6 yet? I know what it is, messed with it in B5, but it wasn't too great. How about this new version? Is it stable? Easy to use? Should I avoid it or is it worth it? If I do use it, it'll be on my network: have 7 computers of various processor speeds/ram, from 512 mb ram, 994 mhz,  to a turion 64 (2 gigs ram, 1.81 ghz). Will this cause problem? Just want to know before I spend hours/days rending this particular HDRI scene.
