Fair enough. I'll have to poke at dbus a bit more then. Our option to support
Bind via LDAP is pretty straightforward, but memory size-wise Bind is a
monster. As I play with Samba on embedded systems, I do understand your
concern for size constraints.

To be honest, if we go and implement enough of DNS to support that part, it
probably makes sense to go the last step to being a full DNS server
ourselves, which would allow us to easily handle all the encryption required
for the client-sent updates.

option I could work with.
