i would create a macro which calls an agi.  The agi searches the CDR 
table (mine is in sql) and calculates if the call can go through.  Then 
i'd call this macro from every extension in the dial plan just before 
the dial cmd.

It depends on the number of simultaneous calls from within the same 
context.  The agi can return a number of seconds (calculated from sql) 
which the dial cmd can use as an absolute limit and after that amount of 
seconds it can hang up the call (see S or L flags).
