So if QtRuby and Qyoto were derived from PerlQt, would it be possible to have 
a dual licensed GPL/Commercial version? The commercial part wouldn't include 
kalyptus as that is GPL, and it is only needed to generate the Smoke library, 
of which the runtime part is MIT licensed isn't it? I ask because I get the 
feeling that the Qt4 version of QtRuby might be very popular and there might 
be sufficient demand for a commercial version (and maybe PerlQt too for that
