I have no problem doing that, just not sure that everyone would
appreciate the spew.  I like it for exactly the same reason,
troubleshooting remote systems.  

What I'd really like to do is revamp the debug code so that it 
can be enabled/disabled on the fly rather than requiring that 
the driver be compiled.  Adding some performance stuff would 
be awesome as well.
