Combine tether internet and broadband connection?

[creedo]

From what I've read while searching this isn't happening. And yet... Gentlemen, we have the technology™. I'd like to combine the bandwidth of my mobile internet with my computer's broadband connection.

So far when I google this I get a lot of people asking how to speed up their tethered connection, and a lot of people asking how to combine two cable/dsl connections. But how can I combine 1 wired connection and 1 wireless-via-USB connection?

Windows says I'm connected to both right now when I look at my network icon. But of course my NIC isn't sucking bandwidth out of both, my download speeds are exactly what they always are when I'm using cable alone.

I guess the combination of two connections is usually done with a load balancing router, and I got some software that claimed to work the same way called Multiconnect. But of course it isn't really the same as adding the two connections together. Instead load balancing just seems to be farming out one download to one connection, and another download to another. It CLAIMS it helps with torrents, where you've got dozens of connections that can be balanced.

That's what I'd like to get working but I saw no improvement. I'm not really sure the program even "sees" my cell connection since it's coming in through USB.

Anyone at least able to tell me for sure it's not possible, or needs special hardware, or whatever?
