The question of how to connect Groove to the "outside world" has several answers. I'm constantly amazed by Tim's ability to cook up code overnight: he's now running a webservice inside a Groove tool, with bidirectional Web access. This is really powerful - a "view-level" parallel of the "model-level" SOAP stuff we're calling Edge Services.

Luckily Tim has a Web-accessible (dynamic DNS at "kicks-ass.net") machine. My main Groove device usually sits behind a firewall. To solve that problem, the Edge Services piece will have "always visible" access points relaying to and from your client in much the same way Groove's relays already work. For a Web system like Tim's, it might be cool to have a reverse-proxy (cacheing?) do the same thing. Or even to bake Grooveness into dynamic DNS (so, for example, a "grooveTelespace://" canonical URL could be served by any online member of the space, or by any device running my account).
