Why not recompile VIM for Python 2.2?  The job is pretty simple,
download the source, and runtime files, add a few patches (there have
been, at my last count, 474 patches since 6.1 first came out, so
you'll miss out on plenty of fixes/features if you just get the plain
binaries), edit the make file (a simple task to point at python22.dll
instead of python21.dll), and compile.

The source comes with plenty of makefiles for different compilers, so
if you have M$VC that's fine, but you can also use MinGW which is
free, small(ish) and pretty easy to use.

There may be times when Python developers really need different
versions installed (as opposed to developers that use Python), but for
normal usage, the fewer complexities the better.
