Yaay!! Good to see that someone has picked up the project!! As you say, it would be a shame for it to die a slow death.. I use MRemoteNG every day at work.. There are a few quirks here and there, but I've become accustomed to those. The main annoyance is the integrated IE engine no longer works for most things so I have to use the External Launcher for these WebUI connections but even that is not a show stopper..
Good Luck with your new roadmap.. I hope I'm not the only one hanging on for the new releases..
