Evaluation of Screencasting Software (SCS) including webcam support
This was made using the free version of Collaaj which allows a 2 minute recording to be uploaded. This video took up about 12 MB so theoretically one could store around a hundred 2 minute videos (actually less, but lets not quibble).
It would also be good to play around with the kind of mouse used. This would need to be done in windows (or whatever OS) settings. It is possible to download and install custom mouse pointers (see deviantart.com, search for mouse cursors, go to personalise etc etc).
