	One could always send a session-limit in the radius
authentication to keep them under their usage for the month, including
sending something that terminates the session at whatever you call 0000
for the start of month.  this obviously could cause a spike in auth
requests around 0000.  the other choices include intelligent
accounting software that can take this situation into account.

	I've not used it in years, but radiator was nice back
in the day.
