Junio,

That's the kind of feedback (and pointers) I was hoping for :)

So is it fair to say you are suggesting:

1. Talk to 'torrent or something' folks to see if they have a scheme in use

and

2.  If not, 'gitoid:${hashtype}:${hashvalue} - like:
     gitoid:sha1:261eeb9e9f8b2b4b0d119366dda99c6fd7d35c64
     would be a better choice
