Topics for BarCampBankSF3

I know there will be many different topics debated, but here are some topics I would personally like to discuss at the next BCBSF3.

• Automatic discovery of payment methods / currency services accepted by buyer/seller.
• Ripple-like settlement using OpenTransact.
• PAN to URL (same as EAUT & Webfinger but for card PANs instead of email)
• OpenPOS
• PROWL/Twollars-like publication-oriented transaction processing
