Hi folks,

I've finished next FreeRADIUS module, rlm_backcounter, which can be used to 
implement various end-user limits basing on counting resource usage in 
defined time period. Seems like classic monthly bandwidth usage limits, eh? 
Not really, it has a bit more to offer :-).

Main differences to the classic approach are: counters count back, they can be 
resetted for each user individually and each user is given two counters - one 
being periodically resetted by the module itself, and one which it can only 
decrease (a "prepaid" counter).

More information:
SVN repo:

The code has just been finished, so be sure to test it before using in 
production environments.

BTW, could someone from the FreeRADIUS team contact me in regard of putting 
references to our open source projects and commercial support on the 
project's website? Sorry - couldn't find any contact information on this 
matter there.
