I think it might be better to bridge HAL (or perhaps at the D-BUS level?) to
an existing, working, secure, well-designed service discovery system. Lots of
people have done service discovery, mostly not very well. Normal complaints
are that the service discovery system doesn't provide the right level of
functionality, or that it causes way to much network traffic.
I suggest Service Location Protocol v2 (RFC2608, RFC2609, RFC2610, RFC2614 and
a few others).
