Is there any way to bond two TAP devices in Windows XP into one network device?

My ISP is, in theory, providing me with a 5Mb/s connection. However, my OpenVPN tap device can only reach ~100KB/s. However, I've tried connecting two devices, and each one can sustain the same 100KB/s.

In Linux, I can bond them together and get, for all practical purposes, a 200KB/s connection. Is there any way to do this in Windows XP?

Your ISP is likely providing you with an asynchronous connection so that 5Mbps connection is likely around 500Kbps to 1Mbps up, 5Mbps down. 100Kbps throughput on a VPN connection isn't that horrible, what with the encryption overhead, etc. – gravyface Aug 24 '10 at 17:46
Sorry, I should have clarified that the 100KB/s is the download speed. By running two downloads over two tunnels, I can download 200KB/s easil. – Mikeage Aug 25 '10 at 5:26

There's no way to accomplish this in Windows without additional software. I'm not aware of any bonding software that would work on OpenVPN TAP interfaces (though it might exist).
