Yes that's the biggest barrier to python 3 adoption. There are
just too many tools that have not been ported yet.

You can do it but it's a rewrite with other modules.

Yes via the subprocess module. You can execute any program that 
reads/writes to stdin/out and access the output. Its not exactly
pretty but it works.
