But overall the technology behind DNSSEC is very solid and is not the 
deployment challenge.

There is one key problem with DNSSEC to the user's system: 1%+ of the network 
rejects it, because the user is behind a device which blocks 3rd-party DNS 
requests and forces all requests through a non-DNSSEC-supporting recursive 
resolver.

Yes, this is an issue.  Wes Hardaker, Olafur Gudmundsson and Suresh 
Krishnaswamy have done a good job of documenting this and other related issues 
in this I-D:

(And they are certainly open to comments and feedback on the draft.)
