We are doing all NAPTR/SRV/A queries at the authoritative nameservers of
the domain because there are routers which fail to respond to NAPTR/SRV
queries, which obviously causes problems. It seems however from what
you're saying that other networks allow a user to query only the local
nameserver. We will take this into account and try to come up with a
solution which solves both problems, although at first glance this does
not seem easy.
