Why is fopnu not open source?

Is the fopnu protocol open? Can we develop our own apps compatible with the fopnu protocol?

There are no other clients using the proprietory Fopnu protocol at this time.

I too would like to see some information released in this area so the protocol can be examined and perhaps any implementational weaknesses highlighted and new feature support for the future explored but open sourcing will offer nothing of current benefit in my opinion.

The developer of Fopnu has traditionally kept all information on the various protocols he has designed and the src code used within his network creations to himself as is his choice and perogative, honestly I dont see anything changing at this time to alter that situation.
