One of the long-standing Qt issues for some developers is the licensing
issue. If you want to do commercial software development with Qt, ya gotta
pay. It's not a lot of money, but it's not free, either. Since a majority of
Ruby developers are developing free (as in free beer) applications anyways,
this may not be a big issue, but I though I'd bring it up.
