Well I may go down in flames for this, but what the hell..
How about using Flash as a cross platform player? FlashMX can dynamically load
JPEG images now directly at runtime. For Webcam, polling still makes sense, but
if you really want 'push' open an XMLSocket in Flash to talk with the server.
Although called XMLSocket, it does not have to be actual XML streams. It just
means the connection stays open until closed.
Oldes' wonderful %make-swf.r can also be used a potent server-side tool in this
scheme. It can generate SWFs from images, as well as all sort so tricks to embed
Actionscript, buttons, PNGs, localConnection object, dynamic timestamps,
metadata, whatever..

LocalConnection is incredible. Makes it trivial to have real-time event passing
between people using flash movies, as long as they are on the same server. That
means you can be sure people are looking at the same thing at the same time..
browsing or updating image sequences etc.
Once you opt for an ActiveX inclusive solution you may as well really enjoy a
modern Flash format for all its virtues.
