I have been working on an accounting module to dump data directly into Couchbase as properly formatted JSON documents.  I have tested the module under decent load (100+ requests per second) and it seems to perform as expected.  The code currently lives in GitHub ( https://github.com/leprechau/rlm_couchbase/tree/freeradius-master ).  Please disregard this message if this is not the proper place to post such things.

Thank You,

Aaron
