EQL is a bandwidht eqalizer. If you have two modems dialed up it will do its
best to equalize the packets sent down each device so that you can get double
the bandwidth if you are maxing out the modems. Its similar to but not
equivalent to multilink PPP which is essentially channel bonding. I've heared
some vague reports that this stuff works well with the so called ShotGun Modems
that were on the market a few months ago.
I doubt if this is currently setup to work with NICs. However, if you want to
do that, check out the www.beowolf.org web page for the Channel-Bondign patches
to the kernel. Channel bonding is one of the core technologies used by Beowolf
clusters to get high performance connectivity between nodes in the cluster.
I've done this myself and it works beautifully. I was able to channel bond
4 100Mb ethernet cards together successfully. Much cheaper than gigabit
ethernet.
If you are intersted in just channel bonding modems, check out Babylon v1.4
that was just released from Spellcaster Telecommuncations
(http://www.spellcast.com). They have some beta support for channel bonding
modems in their current software release.
hope this helps
