I don't own a web-cam but anyone know what would happen if
you replaced the IR LED with a diffused red LED and shone it close to a web
cam.

I don't think web cams record an analog video stream...
and if they did the compression would mangle it beyond recognition.

Starting with a normal IR R/C with its original crystal and normal pulsed
output of 25uS per pulse and 20 pulses per bit of data. Would that produce a
resolvable video stream that could be sent via internet and assuming a wide
enough acceptance spectrum of the receiving phototransistor/diode of a
learner type universal r/c straight off a pc monitor in a dark room.

webcam video uses a much lower frame rate than pc monitors use...
