Well, I know that it is very tempting to "just" port across lots of
programs. But if you are looking to solve an actual problem (in a business
or "just do it" sense) and there is nothing on Plan 9 to help you with that,
then use Linux or Windows or OSX or ...

On the other hand, if you are really interested in providing functionality
to be used within Plan 9 that I'd strongly suggest investigating more than a
port. Re-implementing using the appropriate Plan 9 approach would be way
more beneficial.

:-) Recompile.

(The usual argument to counter this approach is that security updates to
underlying libs are easier to get out across to everyone, while at the same
time completely ignoring the depths of DLL Hell and the myriads of
wonderfull new ways to break perfectly fine software all over the place. Me,
cynical, noooo! :-)
