looking for ideas about how to create a constant data stream

Hi,

I'm looking for a good way to create a constant data stream that will occupy a 
bandwidth of about 2--5Mbit/sec between two remote hosts over the internet.  I 
have full access to the hosts involved.

My first attempt to use scp to copy data from /dev/null on host A to /dev/null 
on host B, but scp says '/dev/null: not a regular file'.  If something like 
that would work, I would be able to limit the bandwidth of this transfer in 
the router(s) involved so that it won't occupy all the bandwidth.

Of course, it would be better if I could limit the bandwidth on the sending 
side rather than dropping packages. I could probably write some program to do 
that, but since I have never programmed such a kind of network application, it 
would be rather time consuming.  Maybe there's already a kind of tool around 
that can do this.

I need this to work around whatever settings my ISP has made 3 days ago that 
block my VPN connection so that I effectively can't reasonably work anymore.  
I do know what the problem with the connection is and that occupying some 
bandwidth would unblock the VPN; only there doesn't seem to be anything else I 
could about it.
