Somebody should be whipped, either for:

1) If you can find a network where that matters, even in the slightest,
the oerson responsible for the design and/or maintainance

OR

2) You, for making even this aged arch-pedant wince. :-)

Seriously, can I also add that RADIUS interim accounting is almost
essential in this scenario. Real world accounting and session boundaries
mis-match badly making it almost mandatory to use interim accounting
records to get an approximation of what the figures look like from
a billing perspective. I'll also add "watch out for missing records"
- I've found RADIUS to be the lossiest network protocol per foot of
cabling that I've ever used.
