Presumably you then have multiple DSL lines from different ISP's coming to each site. This is NOT a solution used with a single ISP to increase incoming Internet bandwidth from that ISP. In theory, it should be possible to duplicate this with ppp under FreeBSD, you create a config that runs multilink PPP over TCP. PPP-over-TCP is already supported in user-mode ppp as is multilink PPP. You may have to make some modifications to the ppp program itself, but most of the work has been done. My only caution though is that if one circuit path between each site has a tremendously higher amount of Round Trip Times on traffic between the sites, then your link is going to favor the circuit path with the hightest speed with most of the traffic, so you may not notice any speed increase.
