Four more gpl enforcement cases

Today I've finalized my preparations (paperwork, etc) for passing four more gpl violation cases off to my lawyer. As usual, I don't state the names of the vendors/products at this time.

There has been quite some amount of backlog piling up, as I've been busy with other (more interesting, to be honest) stuff in the netfilter, openmrtd and OpenEZX world. Luckily we're now using RequestTracker and hopefully don't loose any reports of violating products.
