I have developed myself a similar setup, but i used a perl script with 
snmp pass_persist to retrieve the data via snmp feed it to MRTG and then 
display it with a CGI script, since i changed jobs recently i made some 
changes to the setup and was thinking in creating a sourceforge project.

But i don't think it is ready for that yet, i mean, it is working 
beautifully for me (and in my previous employer) but there are some 
rough edges to address first.

Btw, the setup generates TC, iptables and MRTG configuration from a 
config file.

I think it is time to see how can the setup be improved.

I have never heard of this, must google it.

I really never tried to write a better tool, with less 'tc -s' parsing, 
don't have the time or incentive to hack the needed code, so can't help 
you there :-)

I can forward you the software that i use with some documentation.
