My personal experience I could not do it on my MBP that shipped with 10.5 and the optical drive died, when I needed to wipe the system. I tried both the Apple 10.5 installer and the disks that shipped with that MBP when I put those disks in my newer MBP that shipped with 10.6 and tried over firewire and network. Both times it simply would not let me run the ^&*$#! software from the newer laptop even though I did not want to install it on that. I like to hack, OC and do other warranty voiding voodoo but I don't recomend it to everyone.

As far as Studio goes Daz has not developed DS4 to run in Lion, and DS3 dev has ground to a halt since the first quater of 2011. but the Daz forums have many irked Lion adopters who are reporting lots of wonkiness, mostly in DS4.

Poser 9 and 2012 claims it is compatable, we'll see.
