Since we're talking about DHT's, does anybody know what happened to OpenDHT? That had a lot of buzz and activity at one point in time, then just kinda disappeared.<p>And on the same note... is there a generally available, sort of "free for all" DHT system out there now? If not, what stops one from existing?<p>Just curious, as it seems like DHTs have lots of uses, but it seems redundant for every app that needs one, to re-implement their own DHT network.
