I'm not sure when/if I'll have time for this; but this ought to
be possible:

	GIT_DIR=$HTTP_URL git <any read-only command>

And possible without existing admins to setup or change
anything on their server.

Right now, I could do it by setting up a WebDAV server
and using fusedav[1] on the client.

But, not everybody runs a WebDAV server which allows PROPFIND
for listing files...  However, info/refs and objects/info/packs
can give us all the info we need without needing PROPFIND.  All
we'd need is the common GET/HEAD HTTP methods for read-only
access.

git doesn't need mmap; and curl + Range requests ought to be
able to get us what we need to emulate pread.  It'd be great for
low-latency LANs, maybe not so great with high latency; but
probably better in many cases than cloning a giant repo to cat
one blob.

Also, cloning on a static bundle ought to be doable with:

	git clone $REMOTE_OR_LOCAL_PATH/foo.bundle

And yeah, it also sucks that bundles double storage overhead
for admins; it would be nice if I could use bundles as alternates
or packs...

Anyways, all of this is probably a lot of work and I don't hack
much, anymore.


[1] I have many patches for fusedav, and the debian maintainer
    seems dead, and upstream's moved on: https://bugs.debian.org/fusedav
    davfs2 can't do Range requests, so it won't work for big repos...
