Joel picks on Groove — for some good reasons.
I keep picking on Groove, but only because there’s something interesting in there, one of the few technologies that’s interesting enough to care about. Yes, the Groove engineers are architecture astronauts. That’s OK. They’re building architecture. But they’re positioning it like an application and I don’t think Groove will be successful if they do that. Someone else will come along with a P2P architecture and sell it like a component, or make it an open source library (yes, I’m aware of JXTA), and that’s what software developers will use.
Maybe it’s Rendezvous?
