The technology is not patented and there are several freely available 
bandwidth management platforms for Linux. Whether or not the license of 
the code allows redistribution, I don't know. If the code was released 
under the BSD license with the rest of what is in the BQ project, there 
are no issues with this.

I am not sure what needs to be done to port this functionality to a 2.6 
kernel, but I do think that it may end up being simpler to make a new 
frontend for an existing bandwidth management tool.
