Ok, I can imagine that this works but it sounds a little bit complex 
  to code this (we are useing freeRADIUS to), because the NAS debug 
logging take place on a other machine. Furthermore the debug output 
is very large and grep'in within it may be slow and also the 
dayrollover looks like a problem. Nothing that is impossible but to
expensive.
My intention is to get the information that I need direct from the 
NAS. This is the only instance that *really* know who is online. I 
do not trust log- or accounting files in this situation ;-).

What Im trying now is to script-telnet'ing the NAS, do a "show 
caller" and search only for "Vi[NNN] [username]" lines in the output 
and igoring all "Se[N.N] [username]" and "As[N] [username]" lines to 
produce the list, because the VirtualInterface only appears if the 
RADIUS send's an ACK - or am I wrong with this assumption?
