I'm not entirely clear on what a service name represents. Is it a 
specific service, or is it the profile implemented by that service? What 
string should represent non-standard services? As an example, my phone 
has a service called "Nokia OBEX PC Suite Services". If I want to use 
that via the DBus interface, I'll presumably need to use the record 
handle anyway?

I agree that always requesting the SDP record first is less than ideal, 
but I'd argue that it's better to have suboptimal functionality than no 
functionality :)
