What software besides iGlasses can reverse the mirror image in iChat?

I'm trying to use iChat to stream video of multiple animators and artists around the country looking at each others drawings, instructions, & messages and settings on their computer screens. The iSight cam's mirrored image produces everything backwards - eCamm.com's software, iGlasses, thankfully, reverses the mirror image making it possible for our artists to read each other's instructions. Unfortunately, the iSight cam's quality is not good enough to read the small type on their computer screens. We can use more expensive video camera's with firewire connections, but iGlasses isn't compatible. Is there any other software we can use besides iChat so we can read each others screens and data using more expensive cams and not having to read everything backwards? Probably a unique need but any help much appreciated.
