I don't want to argue about the numbers. Nobody can say for sure, but
from my "7000+ packages Solaris port" (yes we have 7000+ packages in
Nexenta APT repo now) experience, I could say software already ported in
most cases and upstream tarballs just works. The same true for FreeBSD.
Other OSes will catch over time too up to (once they open sourced).

Lets do not count non open sourced OSes for now.

Sure. When bug is found in upstream, FreeBSD, OpenSolaris or Darwin
developers sends patches this way. But I think packaging bugs needs to
be handled by their maintainers or at least effort needs to be
coordinated somehow.
