DISCLAIMER: I don't have any PPPOE or L2TP user-supporting boxes, so I 
can't guarantee this works :)  That aside...

A quick scrape of Cisco's MIBs shows:
cPppoeSystemCurSessions (from the CISCO-PPPOE-MIB)
OID: 1.3.6.1.4.1.9.9.1.94.1.1.1
total number of PPPoE sessions on the device at the time of polling

cvpdnSystemSessionTotal (from the CISCO-VPDN-MGMT-MIB)
OID: 1.3.6.1.4.1.9.10.24.1.1.4.1.3
the total number of VPDN sessions of type (1=l2f, 2=l2tp ,3=pptp) on the 
device at the time of polling, so if you wanted to see just L2TP sessions, 
try 1.3.6.1.4.1.9.10.24.1.1.4.1.3.2.

Your best bet is to snmpwalk the device in question and see if the numbers 
you get back line up with what you get from a "show users" or equivalent 
group of commands.

It looks like both of these OIDs return an integer value, so it should be 
easy to graph them over time with an SNMP-aware graphing utility like 
MRTG, cricket, etc...
