If you look at Mozilla's Weave project, they're doing exactly that. The time they've spent on Personas pales in comparison to the time they've spent on Ubiquity, Test Pilot, Weave and other Labs projects. Using a computer should be fun, and so I don't mind a bit of ooo-shiny every now and then. It sure isn't keeping Mozilla from getting shit done.

Edited to add: a nice work around that I use for multiple identities in the mean time is to use the profile manager. Run Firefox with "firefox -P -no-remote" to start a separate instance of Firefox with the profile manager, create a new profile, and you're good to go. It is a pain, but as a workaround, I've seen worse.
