Hate to steal any thunder, but... Some of these are pretty answerable.

is os4 multi user capable with usr/local/world rights ?
will the passwds (if multiuser capable) be md5 coded to be compatible to existing un*x systems ?
will there be a ssh2 shell ?
will the tcp stack support nat, routing, etc ?
Unless any big surprises are coming, we pretty much know 4.0 will be a single-user OS, though the little-used file ownership features of FFS may've been maintained in the 'FFS2' reimplementation. (I honestly can't remember.) MD5 is popular and free, so if and when anyone did require a strong hashing solution, they'd have to be a little nuts (QSSL) to roll their own. The Roadshow stack has been claimed very modern, and should certainly handle routing, at least - maybe Ben can remind us of the featurelist for that.
will the desktop be exportable via xwin (vnc is not THE solution) ?
This is what troubled me to reply... Unfortunately, VNC *is* 'the solution' for exporting GUIs not intrinsically X11-based. Some sort of X11 wrapper might not be impossible, but it'd be a heck of a lot of work -- consider how much code it'd take to 'translate' things like non-rectangular windows, unless you're talking export of the entire desktop like an X client, in which case it would be little different than using VNC anyway.
Now, if you really must have the X protocol, I was blathering about
NoMachine a while back... Well, I dropped them a line, and received a friendly response. Basically, their focus is elsewhere at the moment, but they *are* interested in supporting PowerPC Linux at some point (three letters: IBM), and they'll see where they can go from there as the marketplace evolves.
