here's how i checked my work.

I don't see how that checks your work?

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> +trace 1s.de mx

How did google DNS get into this picture?

I do get an RRSIG for the mx of 1s.de, despite a lack of NS records.
But you wrote:

i> vixie@linux1:~/work/fsi/dnsdb_c$ ./dnsdb_query -r \*.de/a/de -l 5

e.de.  A  81.91.170.47

And I only see glue for those:

paul@bofh:~$ dig  +dnssec a 4.de. @l.de.net.
