Andrew,
This is great to see, I’d like to think I could help out, but as with other’s I don’t have much spare time. My use of Firefly is solely on Windows Home Server, and anyway I can increase the integration in that area I would be more than happy to do.
I would also be interested in helping maintain the windows install package (either the current NSIS version) or a port to WiX which would enable a standard .msi package to be generated.
However core mt-daap coding is probably going to be out of my scope at the moment.
Regards, Nic
