As far as I know they already split the software handling the IP's between 
multiple instances (some kind of VPN end points outward facing) - so as 
long as we say, avoid anything that's going to try and 'select' on all of 
them - and keep an eye on other things (like mbufs/clusters/fd's etc.) this 
should work...

Thanks for the replies...
