I would also love to see a Linux or web version. I understand that you have no plans to develop that, I just wanted to add my vote in case more demand might make you consider it in the future. 🙂
In the mean time, I wonder if anyone has tried running the windows version in Wine on Linux? Does it run in Wine? If it runs, I'd be happy to buy the windows version for my Linux computer, but I don't want to buy it if I don't know whether it will be able to run or not.
