Whatever is possible: Floating licenses would be great, - if that works,
we'd have no real need to bundle our software to a certain hardware setup.

Yeah, we are almost certain that SGE restrictions are not enough.
Moreover, our software may run at a client's cluster where she has root

Thanks a lot, I've stumbled onto that already, seems rather helpful.

Thanks a lot! We'll discuss all these topics..

Great! Thanks, your post is of great help :)
