Erk :(

Any chance of digital images of those whiteboards or an IRC session some
time?
I'd ask for docs but that, I feel, might be futile ;-)

Erk, again.. thanks for the reminder :-)

URL?

SWARM sounds good, but then I've only heard a chief protagonists pint of
view ;-)

When will we be able to find out more?

Great :-)

I think a lot of people are going to be using PTK for much more than
just simple content managing and reviewing, especially as time goes on.
If Steve's Model can support SWARM or Chautauqau at a later stage then
great, if not, maybe we need to think more?

Now I _know_ a lot of people will be interested in this ;-)

Again, I know people jumping up and down and clamoring for this sort of
thing in a PTK-like environment :-)

Hope we can all help each other,
