The only thing that comes to mind that would facilitate true aggregation 
of multiple links would be to have a server on very high bandwidth that 
you could create multiple tunnels (IPIP / IPSec / GRE) to and have it 
aggregate the multiple tunnels together and then use the aggregated 
tunnel as your larger pipe to the world and do all your NATing at that 
end so the world would see you from one largish connection.

At least in theory this is sound with Multi-Link PPP.  However I do not 
know of any one that has done this.  I suppose this would be a decent 
service if someone could make it turn key.  Would any one care to 
jointly work on something like this?  I could locate a box on an OC-3 
for testing purpose, but not long term production, at least not with out 
paying hundreds per month.

I suppose such a service should support IPSec, IP in IP, GRE, L2TP, PPTP 
tunnels.  What else?  Would it be better to aggregate the tunnels in to 
one large logical router or rather multiple smaller UML / VMWare routers 
per client so the client could have control over the remote end?  What 
about IP address space?  Thoughts / Opinions?
