Hi Edwin,

In short, yes, the browser lets you run an app. We cannot ignore mobile
devices, so the web is an easy way to go about it.

The surface language could be different, and we could have a live coding
environment. I have a bit of (stupid) example of live Smalltak coding. If
you open


and then copy the link after it gets ?q=... to another tab. You press Cmd-s
in the column on the right, which defines some behavior. Then press Cmd-S
in the bottom area, which instantiates a "Morph". Then if you click on the
blue rectangle, it rotates and grows. You can edit code while others are

Yes, I think the edit-and-observe style development is very important when
you want to build something in a real-time collaborative manner. Existing
Smalltalk implementation would not necessarily supports this mode of
interaction by itself so we still have to invent something there, but as
far as I am concerned, I would say that I am still heavily influenced by
the idea what Smalltalk could be here.
