I don't understand that sentiment at all. Using ssh buys me both
transfer time penalties AND processor penalties. And if I'm
transferring large (like, say, 500 GB) files, then those penalties
(especially the processor one) are HUGE. If I'd rather be using
those three processors in my Sun E450 for something else (like, say,
managing the Oracle DB for the client who paid for the damn thing),
then that's a tremendous loss.

I am a sysadmin for a datawarehousing/marketing database company
where we do transfers of data in the TB quantities over private
gigabit Ethernet as a daily occurence. It's way too damn slow with
NFSv3 over UDP (especially since Solaris using Sun's no-jumbo-frame
ge driver is involved, but that's not the only reason), there isn't
a CHANCE I'd be interested in using GSS-API for this.
As for AFS... has OpenAFS gotten around to supporting > 2 GB files
yet? Is it less of a nightmare than living in a Giger painting
would be to install these days?
(I'm legitimately curious about those things, but one should
probably reply privately, since it's wildly off-topic here.)

But why can't we just set CVS_RSH=3Dssh in the default environment,
rather than altering imported sources?
Or, if we really want the sources changed, why can't we just get the
CVS development team to change them at the source, since it's so
obviously the right thing to do?

That's wonderful and I look forward to it (for home, where I do want
all of the things it offers, not for work, which I described above)
but can you see how suggesting use of NFSv4 on a NetBSD mailing
list is a bit of a no-op right now?
