I fully agree. I hope (expect?) all hyperlinks to be in to a CHK. Other systems should be built on top of this. > (2) SOME application of Freenet will require an SVK mechanism, > and while there may be similar systems with the same properties, > none can be simpler. Well, there is a need for a system(s) that handles 1) Guessable keys 1a) Spam 1b) Valid clashes 2) Updating > Therefore, I think that regardless of debate on anything else, > these two features must be implemented and spec'd.
