| There's a big difference. web browser activity is typically *very*

| assupmtions get violated, _everything_ goes to h*ll. <wry grin>
| Not just for 'he who' commits the violation, but everybody else who is

Since I run an ISP that is very small time,
has (at this time) only a single T1 upstream,
all my "subscribers" are wireless clients,
I guess if I have more than 2 subscribers,
I am over subscribed?
Hardly seems fair.
