Thanks for your response. It is disappointing to hear that the MIMO
support for 4 antennas will not be available for some time.
Addressing your disappointment: This is a free software project.

If you’re waiting for somebody else to write it, you may be waiting
for a long long time…
Could you provide some more details into why this problem of aligning
the transmit samples will be easier in the new m-block framework? Will
these new packet oriented m-blocks utilize a different interface to
the USRP which will make this alignment-task easier?
There will be a new interface. More on that when it becomes available.
Each frame to be transmitted will have a timestamp that specifies the
time that it is to be transmitted. You still have to sync the sample
clocks and LO’s on the separate USRPs, but there will be a way to
communicate, in-band, when you want the frame to be transmitted.
