How is it "none", given that there are now three separate computers involved instead of two? There would have to be a little extra latency, i.e., whatever there is between appengine and the "sage engine". That said, the internet is pretty fast these days :-). And the scalability of a decoupled approach like we're talking about is a big plus, if it works. By the way, if you haven't already, I personally think you should start a mailing list, web page, trac, etc. for a separate notebook project, since you're already writing code. There's already some confusion about where we are supposed to have this discussion -- and a funny mix of sage-devel and codenode doesn't seem right. > I would like to decouple Sage as the *engine* from the rest.
