SMOP, I'd have thought. As long as each piece of code which handles data
for this stack knows that it's handling data for that stack it should be
able to account its memory allocations.
The tricky part will be networking allocations because a NIC can of course
handle data for all sorts of consumers. But I expect this can be greatly
simplified with a few heuristics - work out how much memory your typical
networking stack will allocate for a frame and tack that onto the total.
Couple of pages worst case..
