the problem is I am way _over_ 1.54 quite often.  and, I have no idea
why. as my original post states, lots of other data backs this impossible
claim.

I use rrdtool's STACK type in the graph for ifInOctets, placing it on top
of ifOutOctets, so the upper boundary of ifInOctets is indeed a measure of 
aggregate bandwidth, and this should never exceed 1.54Mbps, which it does 
quote often.

So if you could explain to me how it is feasible that I am breaking what
I thought was a physical bandwidth limitation, please tell me.
