Interesting.  But:

I may be missing something, but it seems to me that those DNS-host 
FQDNs remain a basically superfluous level of indirection, even in the
records you cited.  This line:

> linuxmafia.com.		2D IN NS	NS1.linuxmafia.com.

...could just as easily have directly cited, instead of
necessitating this line:

> NS1.linuxmafia.com.	2D IN A

...to derive the IP, which is what you need to reach a nameserver.

That is the aforementioned host record, associated with my nameserver's
current IP.  I believe NetSol still retains a fux0red-up, automatically
generated host record for its former IP,, over which
NetSol mistakenly assigned to Don Marti, rather than me, causing me all
sorts of grief.  

In fact, because of this NetSol system, any IP with an associated host
record becomes effectively a damaged IP address, because it effectively 
cannot be cited for new DNS service under a new admin's authority until
the existing host record gets deleted (in order for a new host record
to be permitted).

The first line you cite (above) could have been less baroquely 

    linuxmafia.com.               2D IN NS

...eliminating the need for the second one you cited.  In fact, I
believe that that's what _used_ to be done, though I can't claim to have
reconstructed the details.

My hypothesis is that NetSol's objective is to accumulate host records,
whose high-value admin contact information can then be sold to marketing
