[E-Lang] New Page: Partially Ordered Message Delivery

[Karp, Alan]

Thanks, MarkM, I did find the remark interesting.  If you're interested in
implementing something like this, I can dredge up, or more easily
reconstruct, the protocol developed by David Stephenson of HP that handles
multihop introductions.  In these, Alice grants some privileges to Bob; Bob
grants a subset to Carol; Carol grants a subset to David.  The protocol
arranges for David to be introduced to Alice and end up with the same set of
privileges he would have had without the introduction.
