If you're grabbing bandwidth information daily (and I don't think you
are... see below) you can't limit in real-time.  Tom said he wants to
"limit" bandwidth.  That means he wants to make sure a given machine
can't use, for example, more than 256kbps.  You don't measure bandwidth
over time; that's transit.

Put another way, bandwidth is the size of the pipe; traffic is how much
data you pump through it.

If your house as a four inch water pipe it can certainly use more water
at once than your neighbor's house with a 1" water pipe.  But...
flushing a toilet will still use only five gallons (unless you're in
California, where it will only use 1.6 gallons, but that's another
story).

Here's what Tom (and I) are talking about...

We own a four inch pipe.  We want to create four virtual one inch pipes
inside that four inch pipe.

You don't do that after the fact.

I think Dennis may have the right idea, but I don't know if we want to
spend $3,000, so perhaps we'll be interested in the software.
