With the standard image, if you've set the mux and number of channels
appropriately, then the interleaved channels are coherently sampled
(assuming you are using daughterboards with coherent local
oscillators.)

Regarding the inband code, this has become unmaintained; we've already
removed it on our 3.3 development trunk.  The host code will get
rewritten using the 3.3 message passing architecture.  The FPGA code
has issues (as you've noted), and I think there are some patches
floating around that fix some of them, but haven't gotten integrated.
Eric might have a better handle on this.
