In practice, you can't have a large number of stream endpoints in a single
USRP, because the crossbar and associated logic adds up. Something on the
order of 16 or so might be a practical limit, depending a lot on what's on
those endpoints. If you need to distinguish between more data streams, then
you'd want to use something like virtual channels or prepending your data
with some kind of identifier.

With many USRPs interconnected, you could have a lot more endpoints in
theory.
