Anybody can write a sockbuf driver, without needing any private APIs. See my 
attachment to this bug https://bugzilla.mozilla.org/show_bug.cgi?id=292127 for 
an example. (It interfaces libldap to Mozilla's Personal Security Manager 
(PSM) to let it handle SSL sessions. This lets you use OpenLDAP's libldap with 
Mozilla/Firefox/Thunderbird/Seamonkey instead of the Mozilla libldap. It only 
does the top half of the interface work that libldap/tls.c does, but that's 
all you need. If you wanted your private message handlers to feed back into 
the sockbuf stack, you'd have to implement the bottom half, like libldap/tls.c 
does.)

You just need to write your sockbuf handler and use ber_sockbuf_add_io to push 
it on.
