I'm starting to think we definitely have our man.   On Ryan Walkers facebook page, he has also liked "High Performance Rebuilds (HPR)" - https://www.facebook.com/pages/High-Performance-Rebuilds-HPR/172626666081205

Seems more than a coincidence that the name found in Rusty's PGP key happens to match a guy with the same name with the same interests that also happens to be into Bitcoin.

He does, however, mention here that he's in the US - https://bitcointalk.org/index.php?topic=100217.msg1107119#msg1107119  .  That's not necessarily true though I suppose, but we'll see.  Chasing down some other info as we speak.
