When I ran across this company on a different research project, I thought some of our integrator-members might be interested.

Sharing USB devices over the network, which is a great idea for many reasons (and also sets up USB capabilities for VM software lacking USB support by "networking" with the host OS that has the support). Also scroll down and look at their serial port <-->TCP/IP and virtual modem software too. Seems like someone might have a use for things like this to solve some comm problems, especially with legacy gear. OEM licensing also available for integrating with your software.
