Do we believe that there will never be another media layer which
requires this sort of external resolver? (Or that ATM is dead and gone
from Solaris forever?)
If so, then I'll be happy to support this since I hate leaving around
dead/untested code. But I'm worried that this one might be a tad premature.
Of course, if all the world is 802, then it probably is indeed not needed.
