I appreciate your paranoia :-) We are wary of announcing all the stuff we're planning given that we don't know how long it will take to build yet and don't want to be accused of vaporware. However, we are planning to announce at least our initial product plans pretty soon. (Probably not in a comment on a HN thread though ;-))
I just want to say that I would gladly pay for private npm hosting. Something along the lines of github's private vs public repos would be extremely valuable. Yes, we could set up our own private npm server, but this seems like an obvious thing to outsource to a service as long as the pricing is not crazy. Best of luck!
We've been using Gemfury[1] for our private modules which has worked out well, no problems in over a year of use.. though I'd probably switch over to npm if they offered private hosting.
