Yeah... There are some.

Most notably:

SLirc doesn't seem to like being in an rxvt... It does work nicely in the
latest breeds of XFree xterm, though. In an rxvt, the DEL key is the only
one to delete... It does, however, work for me. But then, I copied the rxvt
terminfo file to be an xterm-color one. Which works fine.

SLirc may self destruct and wipe your hardrive at any time, and/or lose you
money, cause you injury, and kill you, or your children, or both, or all of
them, as well as potentially killing your wife, or disfiguring any of your
friends and family indiscriminately, possibly while ruining your business
and/or your reputation. (Actually, I don't think it will, but it's always good 
to have a warning like this somewhere for legal reasons, I reckon)
