Well, the important thing is, that you have a core lib that provides all
the functionality of the installer.  A thing which linux in 2.5.x has
already done and the libh project for FreeBSD aimed for.  If you have a
BSD licenced core-lib, the interface is fairly easy and can be easily
replaced.  So IMHO, the actual toolkit is not that important.

The problem is not libdialog, but that sysinstall is not easy to
enhance.  It was never meant to stick around for such a long time :-)
