There is no free software right now that does what the Linkproof does -
completely.
For outbound connections, it uses ping tests to figure out which ISP is
closer to the destination, and uses that ISP's IP block as the NAT destination.
Thus, the return path from the web server/etcetera would pass through the
"right" path.
Of course, a kernel programmer can implement such dynamic NAT decisions, or
maybe build some sort of table. The ping tests - or tcp port 80 connect tests
for better indication of congestion - are easier, something like squid's ICMP
tests I suppose.
