Just an update from us here at amicima:

 New releases of MObj, MFP, and MFPNet are up on the website at

  Summary of relevant updates to MObj, MFP, and MFPNet source code since our
    last release (more details are available in each component's CHANGES.txt

     1) We've taken advantage of the extensible keying framework we put
        in the default cryptographic plugin for MFP a few months back, and
        went ahead and added Diffie-Hellman key agreement, to provide
        perfect forward secrecy for MFP sessions.

	The old-style key agreement scheme, using public key encryption
	of secret keying data, is still available for backward
	but its use is deprecated. MFPNet enables the backward compatibility
	mode by default (sending both Diffie-Hellman and legacy keying when

   self-organizing networks over which both DHT-like operations and
   efficient application-level multicast may be performed. More news about
   that once we've got something to demo.
