Hey, good catch. I did not realize they were UDP and incompatible with Tor. He did mention i2p as a possible future option.
Thanks. The info was not readily available as the architecture of OB is not easily discernable. It might be possible to run the OB Server on a remote host and send the client REST requests over the net, but I doubt this traffic is encrypted, or even secure...
I'm warming up to Hoffman slightly after watching this interview:
http://thisweekinstartups.com/brian-hoffman-openbazaar-bitcoin/I think he simply forked Taaki's distributed market proof of concept code (DarkMarket), hired a dev team, and got some rich VCs to fund him. Given his VC backing, I doubt privacy will be a high priority... He mentions in the interview that he seeks to monetize the software by handling arbitration, escrow, etc. for a fee. Perhaps selling the customer/vendor data is also a stealth plan...
