[LAD] VSTGUI porting in Linux

Hi, I'm the author of a free VST called Digits that has a Linux port. Recently, I put out a new version that has a full editor GUI, but was unable to get the GUI to work on Linux because VSTGUI 4 doesn't appear to have a Linux port. What do you think the best strategy (fastest, least code changes) would be to deliver a GUI for Linux users? I see on the JUCETICE site that there's a VSTGUI 3.0 port, and the old 2.2 VSTGUI that comes with the VST SDK has at least some Linux support (IIRC). I don't use any advanced features (just dials, labels, and sliders). Are either of these good options, and which would be best? Input from somebody experienced with this would be great. -Louis
