Well, with all the clients now reporting this machine as a stratum 3 and 
fractions of a millisecond for an ntpq -p, and this machine reporting 5 
servers and  one BCST at a st=16, and it goes out on the net and checks 
all servers before ntpq -p is completed, take 5 or 6 seconds to do that, 
I'd have to say its working. dd-wrt hasn't an ntpq -p output, so I've 
left it to its own devices, listing its server as pool.ntp.org. It 
doesn't seem to have a switch to turn on .BCST.  That does seem odd as 
ISTR seeing it in an older version.

So I think I've done my part to reduce the load on the debian stratum 2 
servers pool. TANSTAAFL.
