It is.  Everything is logged.  You can either use the 'last' command [man
last(1)], or write your own interface to the last log [man utmp(5)]. Both
of these options are trivial.  I am not as sure what to do if you want to
know byte information, a simple approach may be to have their logout
script call netstat, ala: 

       netstat -b -I INTERFACE

(where INTERFACE is their current interface--i.e. their ppp interface, do
'netstat -i' to see them all)

You may have some problems in determining the interface.  I'm sure I could
figure out a simple way to do it, given enough time--of which I have not
much of :)  This should at least give you some pointers of where to look.
