O'Reilly is hosting another P2P Conference in Washington, DC from Nov. 5 to Nov. 8. There will lots of interesting talks, but that's not what I'm here to push.
Tim Allwine and I will be presenting a talk on an XML-RPC system that we built for an internal O'Reilly system. Most of the talk will be about using XML-RPC and what to watch out for with Web Services. Of course, I'll be shamelessly hawking my XML-RPC book because I'm a corporate shill.
So, if you're in the DC area and want to learn more about XML-RPC, please drop by.
