Method to Monitor Shared SSL Bandwidth?

To my knowledge when using a domain to host Shared SSL for our accounts there is yet unfortunately no method to determine bandwidth used by individual accounts through the Shared SSL host.

i.e. the ability to determine bandwidth for the user 'someuser' through a Shared SSL host:
https://securehost.com/~someuser/

I know that Shared SSL is not recommended but we have to be competitive with those that do offer it and customers do require it when they know it is available elsewhere. I also know this is not recommended over a Wildcard Shared SSL but we can't go that route either.

I would imagine there is a useful access log tool to make this easy to monitor. It would be very beneficial to be able to easily determine which accounts are consuming the most bandwidth. Any ideas?

 

I'm suprised more people aren't interested in a solution for this since this is the most difficult part of managing precious bandwidth usage. Without a method to monitor this, users can leach unlimited bandwidth without a way to find out what's going on. This is not acceptable. I'm considering writing a log parsing script. I could do this fairly easily with PHP but I'm too limited with other languages.
