Uh, what are you expecting in the way of suggestions?  Either the tablet
is sending a continuous stream or it's not.  If there's no non-stream mode
that will give you the information you want, it's going to have to send
a stream and *something* will have to receive it.  If you don't want your
workstation to have to handle it, you need your black box.  How else?
