Metadata has been implemented in-house. I imagine it will be a few weeks before we release it into the wild, though, as we've been working on tweaking the way it fits in the protocol.

Swarmed downloads are not the highest priority item at the moment, but we'll probably do that at some point. Can't give an estimate now.

BTW, LimeWire has been doing a fair amount of research on a novel query routing scheme. This will hopefully be available for beta testing in a few weeks. It's cool...
