Had a delightful chat last week with Craig Raw. He is, obviously, a proponent of open protocols. It's something I assumed, but I also assumed nobody else would want to run this service! Still, building independence in from the start is important.
The second key takeaway is that this should be an Electrum protocol extension! That makes life easier for users, (no extra dialog to choose a Century Metadata server) and for wallet devs, who already use the Electrum protocol.
So I read the Electrum protocol spec. It's restricted JSON-RPC (no \n, except at end). Fairly simple, easy to extend. Looks looks a good fit...
