I do like that ESFQ supports flows based on IP.  However, Alex says in 
http://mailman.ds9a.nl/pipermail/lartc/2002q2/003963.html that it's
poorly tested and to expect b00ms.  My environment is production, so I'm
a bit tentative to install something like this.

Can anyone here tell me what their experiences with ESFQ have been like?

Cheers,
Jason.

I have a different proposal.
I think you should use ESFQ, always based on the internal IP address,
i.e., in the outbound direction base it on source, inbound use dest.
(This is to separately share upload and download bandwidth.)
That means that someone trying to use small bandwidth will get it
right away while those trying to use a lot will have to share it
equally with others.

I'm not optimistic about the other schemes that have been suggested:
- identify good ports 
  Then people will start using those ports for the bad stuff.
- identify bad ip addresses
  Then people will go around borrowing each others computers 
- even a separate class for the residence halls
  Then people will go to the academic buildings to use the computers
  there.  At a college I'd even expect that faculty members would
  let students borrow their computers, so there's not even much
  point to giving faculty a separate class.

It's true that this might cause trouble for people trying to do large
downloads of important stuff.  But are you supposed to know which
stuff is important?  When people claim that what they're doing is
important you can put them in the important class and tell all in
that class who the others are and that they're competing with each
other - so complain to each other before they complain to you.
In fact, I'd try to monitor the usage of such people and distribute
the results to them all, so they know who to blame.
When people complain about others whose stuff they think is not 
really important you can let some higher academic authority make 
the call.
