pppd calls /etc/ppp/ip-up with the following parameters:
 interface-name  tty-device  speed  local-IP-address remote-IP-address ipparam

pppd already counts the number of bytes in/out at the end of the connection but 
you'll have to code the rest of the logging features. Couldn't be too tricky.
A nice to implement it is to make pppd call the ip-down script with the added
parms, then it won't interfere with the already existing code and the kernel
guys will probably take a patch for it so you won't have to recode everything
when a new pppd is released.
