I get that you have a lot to do to get this program to beta stage, and I can live just fine with it tied to windows, as it is, so no worries, I definitely don't want to ask you to sacrifice development for a linux port. as far as WINE goes I have tried it a few times and, at least in the past, it complains about wglsharelists failing and would frequently crash and fail to create a toolpath. Perhaps I shall try this new version, as you have made a great deal of changes since I last tried and so has WINE. If it works I'll let you know.
