Controlling multiple USRP 2 on the TX path

Hi everybody,
just wanted to know if anything like this was done before by anybody:

The idea is to control multiple USRP2 from one single host, over the
very
same Ethernet link.
Like… the closest possible thing to delivering them a phy-level copy of
the
very same Ethernet signal and having them transmitting the same samples
through whatever front-end daughterboard at whatever frequency.

Of course I understand that some bidirectional communication cannot be
avoided at least at instantiation time but, provided that we can do
that,
would it be possible afterwards to deliver multiple USRP2s multiple
copies
of the same Ethernet frames while having them all transmitting (for
sure,
I’m thinking about a tx-path-only configuration) the samples contained
within ?

I don’t really know myself if it is possible but, in case it is, that
would
be opening up unprecedented usage possibilities for the entire USRP2
system.

Thanks to all readers of this question

Best regards
