I had an interesting thought: Would it be somewhat possible to increase download speed (and potentially upload speed) like a download accelerator does, but using a socks proxy that splits your traffic over 10 concurrent SSH tunnels? It wouldn't have to be too sophisticated due to the nature of how this would work; you could simply have a program split the packets(?) over each tunnel with a SOCKS proxy frontend. In theory, it should work nicely. Is there anything out there that does this?

If your download speed is 1.0Mb/s you wont get more than 1.0Mb/s... – dashboard Apr 8 '13 at 1:47
Why would that increase your download speed? – David Schwartz Apr 8 '13 at 1:51
@dashboard While I agree with what you're saying, I'm in a situation where my ISP is cheap (or broke) and has way less bandwidth than they should. I am able to get better speeds from servers that are perfectly capable of uploading at 10mb/s with a download accelerator, whereas usually I get 1/10th the speed I should be getting without a download accelerator. – Clay Freeman Apr 8 '13 at 1:51
ok so the limitation is your isp? you realize that if your isp has a 10Mbs connection for 10 people that if all 10 of you are on and your pulling 5.0Mbs down, the rest of the people will have to share 5.0Mbs... – dashboard Apr 8 '13 at 1:55
A download accelerator can not actually increase your throughput. If you can get 1Mbps max, then all the download accelerator does is give you pre-cached content faster than your ISP can fetch it on its own... – AthomSfere Apr 8 '13 at 2:22

A tunnel encapsulates IP traffic inside another IP packet, which incurs additional bytes of traffic to transmit and receive. As well, on either side of the tunnel, traffic will incur delays as it's wrapped and unwrapped. Oh, and since traffic through a tunnel has a smaller MTU, additional overhead is incurred here as well. So, I cannot think of a situation where this would provide an speed advantage.
