the server doesn't currently do the emulation (although it probably should
in the future...)

that should be sufficient, yes.  the original idea was to set it up so
that a flag passed to the aed driver at config time would set the
emulation.  something like:

aed*    at adb?	flags 0x1

i think scott wanted the default to be on, tho, so that's how it is now.
in all reality, the flag should probably be patchable as well.  there are
a number of improvements on the ADB subsystem left to do, tho, including
getting wscons attachment fully working.

let me know if you have any more questions.

later.
