Hey Markus, For the most part we are looking for door #2, currently running eclipses. In fact, there are a couple usecases in that space. One is to find existing agents that can be asked to do provisioning operations. One example here is double click on a short cut or hitting a web link. That would run a small program that does some discovery and then having found an agent/eclipse, talk to it to do something (open file, start something, provision something, ...). The other that is related involves "kicking" a running Eclipse when the p2 agent has updated the profile being run. Here the profile has been changed for some reason and the agent wants to discover all running instances of the profile and tell them about the change. Largely the same but driven slightly differently. Of course, since we have the potential to manage things remotely, woul dbe good to discover and kick things that are remote. Actually down that front there is also the desire to discover artifact and metadata repos that are available in the network.
As for discovering things on disk, that is interesting as well for some initial install cases but is not on the top of the list. Its great that you are interested in helping here. In particular, can you point to some easy example code of both what someone has to do to make themselves discoverable and what someone else has to do to discover people? Perhaps a simple app that starts up and advertises and then another app that starts up, discovers and sends a message to the first would be an excellent example?

There was some discussion around a Google SOC project as well as the use of commands and console integration. It would be good for someone to prototype an actual working setup here so that we can kick around various options and approaches. For the first cut there does not seem to be a need for doing native stuff (seems like an optimization).

Is the main use case to discover non running Eclipse installations located somewhere on the file system or is it to find other running instances on the same (or remote) machines? The first use case was worked on during the GSoC project of Ogechi Nnadi (Remy Suen and me as mentors)[1] which is not yet ready for productive use. Pascal and I had done some initial requirements discussion before the student started, but nothing really formal. The second use case can be handled by the current incarnation of ECF already (1.2), though we plan on simplifying the API [2] as well as adding at least one additional remote capable provider. Technically both use cases are hidden behind the ECF discovery API since it doesn't distinguish between local and remote discovery. But at least the GSoC project hasn't been adopted to the latest ECF API changes yet (it is even still in the soc repo). > > Both I and Markus Kuppe are actively working on the discovery API, and Jan Rellermeyer is working with us on jSLP.
