Slight clarification: they didn't license "a Qt implementation from some 
outfit".. they licensed Qt (there is only one) from Trolltech, the company 
that created it and sells it.  Trolltech also provided support and code to 
Borland during the process since this was obviously a big deal to them.

Yes.  From what I've heard, it's actually pretty hard to stick at the CLX 
level all the time, though.  Borland gets around this a little by allowing 
you to directly access the Qt layer underneath.  Since Qt is fully 
cross-platform, this isn't a problem when doing xplatform apps.
