Traffic shaping/aggregating

[Bruce Dawson]

My partner and I use VPNs to access our employer sites, and we
frequently find that we're bottlenecking on uploads. So we decided to
get a 2nd cable modem so we won't "collide" with each other.

Although it would make sense that she would use one modem, and I the
other; it stops making sense when you consider the various (shared)
printers, file servers and other servers on our LAN that we need access
to in our daily tasks.

Does anyone know of good reference material regarding "aggregating", or
otherwise combining the two cable modem's throughput into a single
network segment (using a router - preferably  a Linksys running OpenWRT
or somesuch)? I'm really looking for a HOWTO type document - or if
someone knows the commands to execute, that would be a good start!
