I've got a little bit of good news about this .
I've got something in my workspace that more or less works. You can drag-drop to TC-server or use the "add-remove" menu on the server tab. Then it automatically builds the .war file and unzips it to deploy to the server.
This is still highly experimental and not ready for release. For example running in debug mode doesn't work that well. Also haven't had much chance to test what happens when you are editing / changing the project while it is deployed.
So this is not going to make it into the upcoming 2.5 release.
After the release I'll probably put the stuff in so that it becomes available from the nightly update site. That way, people who want to have a go, can try it out and provide some feedback and bugreports.
I'll post updates here when something is available to try.
