Well, if you say it fast, it doesn't sound like much, but this is going 
to be a tremendous amount of work.

Let's say you're going to build a distributed system of small applets to
solve educational problems. Would you build your system on top of a 
system of vapourware? (or on top of a complex and continously changing

Since most of our projects are tiny we have very distinct limitations in
terms of time and resources that we can use to write applications.

I just feel that we should husband these resources very carefully.

True. However, the application doesn't exist.

Again, this doesn't exist.

Very true.

Again true. However, the "existential reality" is that it doesn't
