[OpenID] [OPenID] OpenID usage figures

How about devising a dead-simple voluntary protocol where
an OP (perhaps also RP) could ping, say http://openid.net/usage
for the sole purpose of collection of such stats?

  GET /usage?op=example.com&event=n HTTP/1.1

where n is an int defining the event (successful auth, sreg used, etc).

(Can be abused, sure. /usage can check source IP to OP for obvious
system gaming. Maybe that's enough of deterrent.)

Any takers? Shouldn't take more than a day or so to implement. I can
help if there is anyone who can host the service.
