This series (really only one patch, only split because its large) only
contains client parts, not server ones (not seperately or via patching
git-daemon).

And besides the daemon for gits:// was written from libraries up.

Stunnel seems mainly "tunnel stuff using SSL/TLS" type thing and any
support for auth in it seems afterthought. At least that's what I got
from reading the manuals for it.

The way serverside works is quite different from git-daemon. On client
side there are also some virtually inavoidable bidirectional couplings
(breaks layering) between generic and git-specific parts.

Yes, the code is split into two layers, but both layers contain git-
specific details. And the lower layer is low-level transport control code,
that doesn't even know how to configure TLS connection (that is quite
high-level task).

And ssh:// is not git:// tunneled over SSH, the request passing is done
differently.
