There's a Google Summer of Code project to create a 3to2 processor.
That would let you maintain the code in 3.x, and have it automatically
translated on demand so that it will run under 2.x (where x goes back
to at least 5, I think, but I'm not sure).
Of course, it isn't finished yet, so it won't do you any good right at
the moment :(
