Excellent point. It does depend on the traffic type.
Though I don't like to complicated my configs, you can always use CAR (cisco rate
limiting) through an ACL to protect against the file transfer from the core servers
issue you referred to below. It can make sure a high bandwidth xfer won't suck up all
your available B/W.
Does anyone out there know how to limit B/W based on Flow or individual sessions? Or
even just source (where source is random). For example, a CAR where each IP source
gets no more than X% of B/W (still allowing bursts if bandwidth is available). I
think some QOS tagging and queuing would have to be involved.

I'd say that a more significant issue is customer throughput. The nice
aspect of per conn is that it not only tends to keep a decent load
balance, it also limits bandwidth hogs from saturating all circuits.
This of course depends on your desired result. An example in my case is
my helpdesk. They are off two t1's with dsl and dialup customers. I'd
prefer them not to tank both t1's when transfering files to and from the
core servers.
