* Discussion on issues with non-cache-coherent systems. Vinod is
  preparing a presentation for the next Forum mtg. He needs
  input from vendors who have (or will have) systems that are not
  cache coherent or have special memory features.

* Vinod is updating the existing proposal and will send out a new
  version before the Forum mtg.

* Vinod will check with Dan Bonachea if he can attend next mtg and his
  thoughts on current proposal.

* Discussion on how does the target know of completion. Vinod will
  clarify further in new version of proposal and FAQ.

* Long discussion on how to represent the target address. Currently it
  is directly provided as a (void *), which won't work
  everywhere. There was some consensus that it needs to be an object
  of some kind. Care must be taken about scalability issues (don't
  want a process to a hold a list of everyone's addresses).

* Ticket 35 (datatype and Op registration) and 37 (examples describing
  synchronization semantics) were briefly discussed. Jesper will make
  a presentation on 35 at the Forum mtg. Rajeev said having examples
  like in #37 is a good thing; we need to make sure they are correct 
  (he thinks they are).

If I have missed anything, please add.
