Introducing IDE-based tooling, interacting with the S-RAMP repo, brings up several interesting use cases. For instance, allowing an app developer to search for a WSDL in S-RAMP, then pull it down into his/her project (all from within the IDE) would be powerful.
One idea would be to look into writing this as a JBoss Forge plugin. Not only would we gain Eclipse support, but also any other Forge-supported environment. The unknown is how to integrate that plugin with an Eclipse view UI, as opposed to simply relying on the Forge shell.
