Heheh. Elegant, I might even grant you.  But I'm still thinking utilising DNS
to handle call groups doesn't fall into the category of easy... or
user-friendly. Sure, DNS is easy for DNS, as it should be. But mixing in DNS
to handle calling functions seems... odd somehow. 

Just my opinion. I like handy abstractions. I've never found NAPTR records to
be human-readable enough to count as easy. Especially in vi. 

Perhaps Asterisk is just spoiling me in that sense. Its callgroups are easy to
spot in a text file and rather easy to manage.... and, of course, don't rely
solely on DNS (which is another point of failure in a production system). I'm
picky that way. I don't like adding overt complexity to achieve a solution. I
like that to be done behind the scenes by someone more motivated and
interested in the 'how things work' side of the code. ;) 

This isn't to say I couldn't get used to it. But it's like the equivalent of
piping writes on a unix command line compared to an IM client where all the
details of how the communication is achieved is done behind the scenes. They
both get the job done, but one is clearly easy and the other is clearly a kludge.
