current status of other client features via SQL?

hi, just a quick catch-up on using SQL for client configuration... what is the current status of support for 'require_message_authenticator', 'virtual_server' and 'coa_server' options being fed in via rlm_sql - I'm aware that theres ability to name virtual_server but what happens if the field is entry - does it go to the default virtual_server? what work is needed for these client options to be supported via SQL feed into clients list? thanks alan
