This is a pretty good idea.  It would definitely take some doing, but one 
could imagine cutting and pasting lots of code from rpcrt4 and the wineserver 
to achieve it via unix domain sockets... this would definitely be a big boon 
to projects like mplayer and mono which want some way to kick wine around 
from a normal linux ABI environment (seems like a pretty common problem 
actually, I see it mentioned on this list quite frequently).

Although I've contemplated inventing something like this in the past, ATM I 
am /not/ volunteering.  If you give me a few months (or pay me ;)) I will 
probably take a crack at it, but right now I am hopelessly busy :(.
