A multithreaded version of bscp tool for high bandwidth high latency networks. Provides secure and efficient copying of block devices (and large files) between (very) distant machines.

I implemented mbscp to accomplish an intercontinental transfer of an hdd's image over the internet in a reasonable amount of time. While bscp works perfectly for not very distant machines, a high latency connection significantly hampers the transfer speed. mbscp uses multiple ssh connections to utilize high bandwidth connections in the presence of high latency.
