I dumb, I didn't see your pretty linky...
And yes, like I said you could get a download accelerator... They basically use the HTTP resume feature to start downloading @ multiple points in a file, over multiple connections. This could work, though how well your load-balancing works will come into play. Becuase it might stuff both connections onto one NIC. You'd most likely have to open a bunch and hope that some of them split over to the other NIC.
Also keep in mind that places, such as our very own AnimeMusicVideos.ORG do not like DAs since they hog up HTTP connections/resources on the server. So they block use of them. Which basically means you're stuck using a single connection. Though you might be able to download two videos from the ORG @ the same time, going max speed over each line.
Most P2P software has multi-source downloading. Which uses multiple connections. But most people on p2p networks are limited to 16KB/32KB/64KB upload rates. Also there are long queues on many networks. So even if you had 100 connections going but each was only going 1.2KB/sec. You're not gaining anything really.
It does come down to load-balancing to, because it can be hit and miss. So it might overload one card but the other card won't get used... So.. yeah...
Is it worth it for you to spend $250 on ? Or fiddle with linux. Which actually after reading that page I linked to over again, that might not even work for what you want. So X_X! Bah...
