Logging raw accounting packets

[Brian Candler]

I would like to put accounting logs into some sort of database, but store
the entire raw binary packet as well as some decoded attributes.

I can think of plenty of options for the storage: e.g. mysql Blob column,
CouchDB binary attachment, MongoDB etc.  But I can't see how to get at the
raw packet from the freeradius config.  Even rlm_perl doesn't seem to
receive the raw packet, only a hash of decoded attributes.

Is there a module which can do this already, or should I be looking to hack
something up in C?

Thanks,

Brian.
