Screencasting can be very profitable (if you don’t believe me, listen to Profitable Podcasting #6 and know that Don is doing even better now than he was on the call (yes, there is growth in this space, even in the “techie space” if your plan is solid)). The default/defacto/standard screencasting product for the PC is a program called Camtasia Pro. It is currently in revision 5.
It ain’t cheap – but it is very powerful. I’ve been screaming at TechSmith for a Mac version.
I paid full retail for Camtasia 3 a few years back.
