How I believed MIMO works is that it recognizes "where" the clients are
and optimizes which antennas it uses from its multiple antenna array in
order to get maximum throughput around obstacles.

In that case, the smarts are all in the router and the receiver doesn't
need to know about this, so yes, a MIMO 802.11g router would have
advantages working with a Squeezebox that has a regular 802.11g card in
it.

But my impression doesn't match the description in Wikipedia, which
states that both devices must have a multiple antenna array:

http://en.wikipedia.org/wiki/Multiple-input_multiple-output_communications

so if the Wikipedia article is right, the receiver needs to be MIMO as
well.  However, there sure aren't many MIMO receivers out there, so I'm
not sure if there will be improvements with a non-MIMO receiver, i.e.
whether the router can get any improvement without a MIMO receiver.  A
MIMO router with a non-MIMO receiver would be the typical use case for
sure - I would think since MIMO is out of infancy now there must surely
be some optimizations?
