Maybe and no. The goal is to make it work with all current resamplers, but since I'm still working on the frontend, I can't say for sure if all of them will be compatible. The idea is to run them under wine on a Linux server. I did some testing and was able to at least invoke m4 and the default resampler remotely, but I couldn't get moresampler to work. Fortunately, Kanru Hua pointed out why, so I'm sure I can find a workaround. As for plugins, it's impossible to keep compatibility, since they are just Windows executables that get called by the main program. It is possible to implement their features directly on the front-end, though. It doesn't rely on UTAU to work, so VB6 support is not a problem.
