netflow per connection

[Igor Smitran]

Yes Peter, you are right. My fault. I only tried netflow tools, i never used 
those in production envrionment. I just checked and saw that i need to pull 
data from collector, while collector is receiving data from routers. That 
said it is not possible to have accurate data at disconnect. Sorry for this, 
i was hotheaded, but i can't help it, it defines me :)
