We missed the 8:40 bus to the venue this morning, so the video of Eliot's talk starts a couple of minutes in. Also, there seems to be some kind of construction going on above us, so I'm sure the audio will be affected badly by that. Nothing I can do about that :)
Anyway - Eliot's describing the work he's doing on Cog, which will be a modern VM for Croquet/Squeak. I'm not going to go into details on the technology choices here - Niall's report, when it appears, will have all of that. The short answer: Cog will have closures, a JIT - pretty much all of the things that appeared in the VW VM over the last decade.

Eliot's documenting his work on his blog - you can get all the details of the in-progress work there (and Eliot promises to update that with his latest progress soon).
On timing, the fast JIT should appear for one platform in April 2009, with more platforms appearing in 2010 and 2011.
