This is a right direction to go -- but what about situations where it
just can't work?

For example, in the electronic classroom configuration where I teach,
the video output from the podium PC goes to a video splitter which
drives an LCD panel and an LCD projector. Each of those devices has an
optimal/native resolution, but the splitter prevents the use of DDC to
get the monitor specs (and rightly so, because the devices may have
different specs).

The XInFC7 wiki page just says that we need to be able to remember/bind
EDIDs, but there are many cases like this where we won't *get* an EDID
at all, ever, and defaulting to the lowest common denominator is
"decidedly suboptimal". We can't switch entirely to autoconfiguration.
