You're welcome :)

We did contact vendor technical support, in particular to determine 
whether any work-arounds exist on those routers that don't appear to allow 
the DNS settings in the DHCP server to be changed.

However attempts to reach product management types to talk about 
implementation issues were generally fruitless.  I did manage to report my 
findings to Zyxel UK through an existing contact, though.

I'm hoping that some of the vendors will get in touch with me, now that 
the report is published.

We didn't see any direct evidence of shared code between vendors.  We did 
see some quirks that might suggest commonality (e.g. NAT tranlation 
failures) but didn't look for anything to prove a link.
