Too bad they don't integrate with Coinbase.com!
"Green address" means whitelisting addresses from the big online wallet sites because you trust them not to launch double-spending attacks against you. Coinbase would also be a great green address provider.
Shoot me an email (in my profile) if you need a beta tester!
Also can you please please please get American Apparel 50/50 shirts? They're the only shirts I buy now.
