Checking my messages daily, for no particular reason...
Honestly I wouldn't expect to hear anything for quite some time.
From my rather extensive experience with the client, I can tell you that while the client does contain most of the assets, the majority of the game
processing happens server side. Significantly more than many other MMOs, actually. WoW for instance doesn't do full physics serverside (and even line-of-sight is halfassed), which is why client hacks allow people to cheat there -- and why they need Warden. COH does all of that on the server, and the client is designed around that assumption.
Factor two is that this close to the shutdown, you can bet eyes within NCSoft are looking very closely at this community. Discussing working on such a project on an open forum would be a dumb move of epic proportions. Even trading PMs with unknown parties would be risky, and unless a very specific skill set was needed, there would be no reason to do so. I notice that even the one project that I know of that's trying an open approach has gotten very quiet lately.
Even if such a thing were being developed, it would likely be a year or more before it was even ready for
beta testing, much less widespread use.
