Okay, I'd lump that in the category of "non-DNS information".

Mine does all of that except for the last. I don't allow my users to manipulate
TXT and MX records, so it's not really an issue. On the relatively-rare
occasions where an MX change is needed, I do it myself "manually" (using
nsupdate). I also retain control of all zone creation and deletion, which are
even more rare.

However, I don't think your last requirement would be particularly difficult.
Just do an ANY query and display the results.

Unfortunately, all of my stuff was written on DaimlerChrysler time, so
technically it's their intellectual property. But I could give you some
pointers if you want to create something similar. If it's not of general
interest, we should probably take that discussion off-line.
