I have a need to use one laptop for a live presentation (with projector, etc.), but record that presentation on another laptop -- similar to what I can do with Camtasia, only with the recording happening on another laptop.

Is this possible? What do I need to do this? Some VGA device that goes between the presenting machine and the projector? Some USB device?

My ideal requirements:

• The machines must be "standard" laptops (so I can't just add a new card to a desktop, etc.).
• I prefer a hardware solution, but cannot involve studio type equipment.
• I'd prefer not to install Camtasia (or similar) on the presenting machine for two reasons:
  • licensing issues
  • performance issues (sometimes the presentations are machine intensive and I don't want the recording software to interfere with the presentation)

I'd appreciate any tips. Thanks.
