I'm comfortable that these will both come to fruition. However, if you
look on the mailing lists you'll see people saying they'll do X, and X
never happens. If you look at  the git and svn project branches you
will see that even the best developers have lots of ideas that never
make it over the finish line.

So I often have to check what the Linux one is doing as well and sometimes the NetBSD one. Ultimately, apart from struct definitions, very little code will be shared between the platforms.

That would be helpful.

This is a background task, so I can chime in on the weekends.

Cheers.
