Load-balancing IP interfaces - another brainstorm

[Bryan Pizzuti]

Ok, get out the umbrella. ;)  My laptop has an internal 54g card...now, I
ALSO happen to have a D-Link Turbo A/B/G PC card....we know wireless isn't
the hottest thing for high bandwith and stable connections always
(especially with all my stupid neighbors with all their "B" routers set at
the default channel of 6...)...anyway, is there a way to configure Linux to
use 2 network interfaces at the same time, and basically see them as one,
using the bandwidth from both and not losing connectivity unless both fail
at the same time?
