I'm not sure whether I would actually need this but was wondering if user code can get a cell's dependancies?

Sure. The slot on the cell struct is caller-store and it is implemented with my little fifo-queue hack. The fifth argument to an observer is the cell being observed, nil if the model instance slot is not being mediated by a Cell (it was initialized to a constant or optimized away). The default variable name in defobserver if you do not list five is "c".

Maybe we could pass this information along to the javascript.

You mean propagation would happen on the client side? But don't the client nodes always have to go back to the server to get their values?

Sorry, I have a lot of ground to make up on this web stuff. I was thinking the web page would be a pure slave made more responsive by the granularity of XMLHTTPRequest (xhr?).

I've been thinking about the caching thing I mentioned on c.l.l

Caching is certainly possible in javascript. Even the browser's own caching system could be used if we use a REST based system although since we're aggregating events, this might not be so useful (lots of unique requests so less chance of a cache hit). The solution would be to send a list of requests, and in the response, include each request with its resulting updates. Add these to the cache and we should get more hits.

Sorry, ya lost me. :)
