  Absolutely!  Anyone that wants to write cross-version Python code
needs to be able to have multiple versions available.  I'd even like
to be able to have both Python 2.0 and Python 2.0.1 available on the
same $prefix/$exec_prefix -- that can't be done currently.  This kind
of thing is pretty important when you want to take cross-version
compatibility seriously.

  Another excellent reason to support multiple versions!  As more
widely distributed applications are written using Python and don't
want to include the interpreter, this becomes a more noticable issue.
