Home inventory software

I decided to try to go into shareware business on Linux. Many people are complaining that Linux is hostile ground for shareware authors and it is possible so. I guess that Linux users are used to have things for free, well at least I have. But it also gets us to the point where some kind of "boring" software isn't available on Linux. By "boring" I mean in the sense that such software is "boring" for developers to make, and they would probably never do it for fun, but rather expecting some money in return.
