[unisog] Traffic Shapers

We've used the packeteer product for years.  In my experience, you can
use it in one of two ways.  

a) Try to identify and manage every type of application and traffic, and
write rules that apply to each tailoring what gets priority and what
doesn't.  In this scenario you will be constantly looking for the latest
and maybe not terribly stable releases of code, tweaking and tuning, and
generally doing a lot of babysitting.

b) If your LAN is routed by building or class of user (IE dorms versus
classrooms etc.) You can write simple top level rules dropping those
apps that you prohibit, like P2P.  Then use dynamic partitioning, such
that each user gets a slice and nobody burns up all of the bandwidth.
Choose a recent and stable code release and keep it.  In this scenario
it's pretty much set and forget.

I will need to procure a traffic shaper soon. I have it narrowed down to
Packeteer and NetEqulizer. Besides the large difference in pricing, does
anyone have any pro/cons for either device? I have heard Packeteer
requires frequent fine tuning.
