One simple and powerful application for a scripting language interface
in the web is to have the notion of `expires' be an expression that is
evaluated in some safe language. That is: at what point should this
client contact that server in order to update the information
contained therein?

The `expires' expression should be evaluatable in terms of time,
location of client, or a variety of `shared variables', which might
require client-side participation in a state variable maintenance
system, but would generalize the web protocols in an interesting and
safe way.

(The work on Mobisaic at last year's Web conference used this idea,
and I found it attractive.)
