I can certainly add an option to git-pack-file that disables writing of
the index file, and just writes the pack-file to stdout.

Done.

What I actually meant was that it would be useful for git-ssh-push to be
able to pack stuff as a function call rather than execing an external
program, because just sticking git-ssh-push at the end of a pipeline
doesn't work if you don't remember what the remote side has.

					 I'm not sure I
want to write the "parse incoming pack-file" thing, but git-unpack-objects
comes _reasonably_ close (but right now it seeks around using the index
file to resolve deltas, instead of keeping them in memory and resolving
them when possible).

I'm still thinking about this one. I think I'll just do it.

One possibility would be to put a special type tag (like '\0') before the
hash, so that the format is more deterministic.

One problem here is that since we don't know how big the incoming
pack-file will be, in a streaming input environment the receiver needs to
either make the pack-file reception be the last thing it sees, or it will
have to live with the fact that "git-unpack-objects" will read some more
than it needs before it notices that it got it all...

In a completely streaming environment, yes; but the receiving side is the
one sending commands, so you don't run into the next thing unless you're
overlapping requests. Failing that, we can just keep a 4k buffer of stuff
we've already read around; we don't have to worry about reading into
something we won't want to read at all.
