Woah. I missed that one. I thought RabbitMQ was written by the LShift guys, which based on the fact that the LShift website has a big banner saying "SpringSource acquires Rabbit Technologies" is accurate, but is LShift dead, in favor of the obviously spun off Rabbit Technologies? Or is LShift going to continue to be around, but with a few less people. This has probably been discussed before--will search.

EDIT doesn't look like LShift is dead. From the press release, they spun off another company for Rabbit, potentially in response to acquisition inquiries, and will just lose a few people it seems.
