jSLP 1.0.0RC2 has recently been added to Orbit which concludes the new SLP provider contribution [CQ 1925, CQ1926, Bug #200804] for the ECF discovery API.
While implementing the new SLP provider, we have also done a couple of necessary API changes too, which are best summarized in Simplify/generalize discovery API #209774. Additionally a CompositeDiscoveryContainer is ready which allows several discovery providers to be used simultaneously. The only thing left to do, is to integrate the SLP provider into our automated builds so it can go into ECF 2.0.0M5.
Scott who never sleeps has put together an example showing how ECF discovery can be used to find update sites, which is probably of interest to Provisioning/p2 at some point in time.
And if this has raised some curiosity in you, Scott is going to talk about ECF as a whole during EclipseCon08.
