Well, the obvious software difficulty is that the 68881 reg's don't
get saved in a context switch.  But I would find even being
restricted to a single floating point process quite usefull.
The other obvious difficulty is generating code for it!

I don't know about other hardware/software difficulties, but I would 
definitely want to buy one if it worked at all.

ps: Jan, do your or Discovery know anything about ethernet cards for
this box?  Anbody got one they want to sell?
