Exactly. You basically have to either

a) analyze webserver logs (very inaccurate, CPU-intensive)

b) write your own accounting software basing on sniffing, analyzing
   packet payloads for HTTP 1.1 header information and tracing TCP
   streams. This can also lead to a restructuring of you networks to
   be able to sniff.

AFAIK Strato (hosting >500.000 .de domains) does something like b)
'cause they can't afford spending CPU time on their hosting server to
do any accounting... (but this is hearsay).
