Ok, after a little research I think I'm starting to understand. For everyone else:
plwrght currently works for
TechSmith, and they currently make a Quicktime Codec called
EnSharpen, which is advertised as a lossless encoding with high compression. For Windows users, they also sell
Camtasia Studio, which appears to be essentially SnapzProX for Windows. They recommend SnapzProX for Mac users.
They also offer
SnagIt, an advanced screen capture utility.
Morae, which appears to be a software/website usability testing software.
And lastly, the TSCC codec, which is the default codec for their Camtasia Studio software.
plwrght is wondering whether expanding their other products to Mac will also help increase their Windows sales from the extra "Word of Mouth" advertising that they would get.
If I got anything wrong there, feel free to correct me.
Camtasia Studio: SnapzProX currently has the market for screen capture cornered. I've never used Camtasia Studio, but unless you can produce a version that goes above and beyond SnapzProX and still offers a competitive price, you aren't going to go very far with it.
SnagIt: I have yet to see a 'print screen' utility that I would pay for, although, again, I haven't ever used SnagIt. I've never seen a need for any ability that doesn't ship with OS X, but that might be simply because it hasn't been offered to me. I have a Screen Capture widget, but all it does is essentially type in the shortcuts for me, and auto-save them to the desktop in a specified format.
There's my thoughts....
