Can I suggest you look at this as it *may* be the solution for us Linuxers. You probably don't want to extend us formal support, but one of the great things about the old minion was that it could run on our platform too. You make the .jar available and we'll look at getting it working and trying to help other Linuxers here.
Curse Client is written in .NET which makes the chances of getting it running on Linux remote even impossible, which is why I hung onto Minion for so long after it wasn't supported anymore.
Very pleased to see a new version and relieved it's java based (fingers crossed for some cross-platform action).
