You're most welcome!

I hadn't heard of Tkx, myself - presumably that's talking to an Aqua-Tcl binary to bypass X11. Actually, that's kind of cool, I'll have to take it for a spin. :-)

As long as you're considering substantial change to your design, do take a look at the script I referenced earlier. It uses HTTP::Server::Simple and CGI for the GUI. Quick and dirty, but works like a charm.
