I'm currently migrating from Blender 2.49...yeaah.. I was stubborn and reluctant to change since I got so used to it, but the newest version seemed too darn awesome I can't help but try it especially when I saw this feature! Well done!
impressive progress. I hope you complete dyntopo soon.
Have you thought about going back to ptex after this? Would be nice to have it stable in Blender, especially now that pixar released their subdiv technology. Its a shame that Maya gets these features first :(
