Affordably Aggregating ISP Connections?

An anonymous reader writes "Has anyone setup a system to aggregate multiple ISP connections to form a high bandwidth site-to-site link? Load Sharing SCTP looked interesting, but it doesn't look like it has been widely adopted. Multi-Link PPP appears to be more widely supported for clients, but I can't find any good guides for setting up both sides of the connection for a site-to-site link. The hardware solutions I've found are expensive for a small business. Does anyone have experience using hardware solutions from Mushroom Networks (Virtual Leased Line, p2 of this document), Ecessa (site-to-Site Channel Bonding), or others?"

Ask Willie Nelson, he uses Mushroom Portabella

Wired has an article on Willie Nelson's setup in his tour bus running, http://www.wired.com/epicenter/2009/10/willie-nelson-broadban/ "Willie Nelson has tossed the satellite dish off the back of his corn-powered tour bus in favor of a little box that fuses wireless data cards from a variety of networks into a single connection."[Mushroom Networks PortaBella 141]

Mac OS X?

Admittedly, I have no idea if it works, nor do I have any idea how it decides to load balance between the connections.. But I ran across the feature the other day and it looked pretty cool.

In Mac OS X you can create a new "Aggregate" network device from any other devices and, in theory, do exactly what your describing. Again, I just ran across this the other day in Network Preferences and have no idea if/how it works, but it might be worth a shot (especially since it seems a lot easier to configure than a roll your own router with dd-wrt or tomato, though those likely offer more fine-tuned configuration).
