Interesting question, since with dynamic linking, it's the recipient of the
software that creates the, er, mixed work. And since he doesn't redistribute
the in-memory running image, everything might well be kosher GPLwise.
Might well be a real GPL loophole here..... I think I can see an argument to
be
made on the other side, though.... (e.g., it talks like linking and walks like
linking...)

Of course, the ultimate solution to not being sued is to make sure nobody
feels
like a victim of your actions....
