[Interest] PQ Labs and Qt

Hi all, this is probably not the best place to ask regarding an
external product but the question is Qt-related so here you go.

My work group is going to acquire an Evoluce multi-touch screen that's
basically a very large screen with a PQ Labs overlay supporting up to
6 fingers (which is quite disappointing but I'll have to live with
that).

I couldn't find much information on the Internet about this so I'm
asking for opinions and experiences with the PQ Labs overlays and Qt
software. Now, the only thing I know is that the overlay we'll have is
not supported under Linux since PQ Labs doesn't provide drivers for
older models, so I'm stuck with Windows or OS X. Also, I'm told the
overlay's driver outputs cursor in TUIO format. My only previous
experience with Qt and multi-touch dates back to the days when Qt
didn't support multiple cursors so I had to develop my own support for
my own applications, though I have worked with TUIO before. The thing
is that every single Evoluce demo I see around is using exclusively
Windows, and I'm not familiar enough with it to assess the state of
the art.

If anybody had any experience with this combo, I'd appreciate any insight.

Thanks,
