I owned 25% of this hi-tech startup for medical laser threatment, but its products didn't sell, so it was eventually dissolved when it ran out of cash.
For the curious, I still have the company web site here: http://www.codewiz.org/oldsites/sirius/
Besides setting up the IT infrastructure, netwkork and telephony, I did most of the firmware and some GUI development for Sirius projects. Additionally, I coordinated a few external developers.
An interesting part was doing real-time video capture on Windows with a Matrox G400, using a vey early release of Microsoft's DirectMedia.
