Josh,

This is great!

Although it goes without saying, I’m assuming users should also need
to keep in mind that there’s no magic going on here w.r.t. gigE
bandwidth (i.e., one U2 running “wide open” can pretty much consume an
entire gigE port. Now that you’ve got 2 U2’s sharing a single connection
each one (on average) should be run at no more than 1/2 max bandwidth).
right?

Correct, the max rate of the dual setup would be half that of a single
unit. -Josh

It will also be possible to connect both devices to their own dedicated
ethernet while sharing the mimo cable, and tell one device mimo_sync=1.

In that way you can get the full bandwidth (if your pc allows it), and
use the mimo cable only for synchronization purposes.
