Andy - this sounds really cool.  I've been looking for a solution like 
this for some time.  I can't explain what a cool feature this would be 
for FreeBSD.  This allows all kinds of incredible fault tolerant 
systems, and for me, is essential.  Is this code ready for people to 
play with?  Are you putting is under the BSDL or GPL?  More info!! :)
