Surge [1] is scalability focused conference in late September hosted in Baltimore. It's a pretty cool conference with a good mix of operationally minded people interested in scalability, distributed systems, systems level performance and good stuff like that. You should go! [2]
Anyway, I'll be there if there, and are if any other Cassandra users are coming I'm happy to help herd us towards meeting up, lunch, hacking, etc. I *think* there might be some time for structured BoF type sessions as well.
