Gepasi under linux!

Yes, it is possible using the Wine emulator. Download this tarball gepasi4wine.tar.gz and untar it in the "Program Files" directory of your Wine installation. Gepasi will run ok, albeit a little slower. More detailed instructions here (WineHQ). This will do until COPASI is here!
