It is already (git://gerrit.ovirt.org/ovirt-guest-agent).  Barak, is 
there a gitweb/cgit instance?

ovirt-guest-agent is licensed under GPLv3, so you do not need to; the 
options in GPLv3 include this one:

     d) Convey the object code by offering access from a designated
     place (gratis or for a charge), and offer equivalent access to the
     Corresponding Source in the same way through the same place at no
     further charge.  You need not require recipients to copy the
     Corresponding Source along with the object code.  If the place to
     copy the object code is a network server, the Corresponding Source
     may be on a different server (operated by you or a third party)
     that supports equivalent copying facilities, provided you maintain
     clear directions next to the object code saying where to find the
     Corresponding Source.  Regardless of what server hosts the
     Corresponding Source, you remain obligated to ensure that it is
     available for as long as needed to satisfy these requirements.

Of course having a separate repo, and mirroring to qemu.org both remain 
nice things to have.
