Thanks for the plug, Ned.

You can find the single image work I did to support eventual sending here:
http://minnow.cc.gatech.edu/squeak/2410.  As Cees mentions, I am working to
produce the encrypted networking framework (VatTP - 64bit 3DES) which will
then link into the eventual sending framework (CapTP)(with the addition of
the classes RemoteRef, RemotePromise and RemoteResolver and some GC
operations).  I have VatTP working, but I am changing the protocol
negotiation to hopefully match VatTP in E (http:www.eights.org), before I
release it.  

The basic concept is each Vat would correspond to one of Lex's Islands,
which may in turn be one of Croquet's Spaces.  It would be a user space.  I
am trying to provide reference decoupling between Vats, and an execution
semantic to send messages to cross-Vat references (eventual sending).  The
rest of the work in isolating the system is planned to be Lex's work with
Islands.

It looks to be a productive winter.

cheers,
