Not sure why I didn't think of this earlier (or why nobody @ Warpstock did!).
But why don't you set up a VideoConference for WarpStock over the WWW?
 
There are Java based solutions that work under OS/2.
Heck, you can even use a Webcam for live video streaming under OS/2 (IP Cam based).
I use all those myself.
 
But for those of basic means amongst us -
You could set up a web portal so that people still pay an "entry fee" to get in.
That way all they needed to attend would be a web browser and the MPEG or FLASH plug-in. I think even WarpVision might work here.
 
They could submit their questions in turn either via e-mail or voice stream.
No camera needed on the other side.
 
Just like a cyber chat session. If you project the questions on a white board, then Mr. Dvorac could see for himself how huge the OS/2 audience really is.
 
Now I could manage that, monitor my system gauges in one Desktop and follow WarpStock on the other.
 
That way everybody wins!
