It seems they have also failed to deliver. I may be wrong and the team is working hard behind to deliver something big in the right time once demand for decentralized DNS arises, but right now, its a speculation that something good is coming. If team able to deliver in right time, it will certainly be a big multiplier of the investment.
What do you mean with "failed to deliver"? The lack of light clients etc.?
In the last few months there was a lot of work on light clients - there is a working Electrum version (albeit with some pretty nasty bugs still, so it's not ready for productive use) and a Java-based light client. I think once light clients are feature-complete (including DNS stuff) then NMC is ready for prime time, as working with the decentralized DNS would become
much easier.
As it's a decentralized project (without "development behind closed doors" etc. like it's common in centralized coin projects) people dissatisfied with the development pace can participate themselves.
