Synchronizing two USRP2 with MIMO

I have checked the forum and googled the web, but I could not find a
conclusive answer for this question, so I post it here.

Can anybody tell me if I can use the MIMO interface to run two USRP2s
with the same clock? I like to use both as receivers, running each a
DBSRX. For my application it is critical that both devices are well
synchronized, otherwise I would see an artificial Doppler shift/rate,
between the two data streams…
