SubEthaTrack, a site for making SubEthaEdit (formerly Hydra) documents globally available. (SubEtha is the group document editing tool perhaps best likened to an IM wiki. Mac only, alas. SubEtha is becoming the new BBEdit.) The design is: open and share a SubEthaEdit document, then go to SubEthaTrack, which will read and share your document, making it globally available. Then other users can search for documents, and join any you have made public. There's even one-button application launch from Safari. Right now, there are so few docs set up that the search filter is a no-op, returning a list of the handful of existing spaces, but the CodingMonkeys folks have an always-on server hosting some test docs, like a global scratchpad. Lots of latent promise, lots of hurdles as well, including, alas NAT traversal (sweet weeping Jesus, the internet is broken and getting more broken by the day.) I have tried it from a hotel room and a conference network, and am able to join existing SubEtha shared docs over the network, but unable to host any of my own, because the NAT/firewall/router dingus I'm behind drops traffic at the port SubEthaTrack expects to inspect. There was a heady moment in 2000 where we thought the P2P people were fixing NAT traversal as a general solution, but here it is 4 years later, and we're still fixing this problem imperfectly and app by app. For things like SubEtha to work, we need to take into account that the users most likely to need zero configuration tools are the users who are least likely to have a naked IP address.
