HTML FORMs, despite their glaringly obvious limitations as a UIMS,
are available to essentially anyone able to access the Web, whatever
platform they may use. That's a very valuable assumption, which
can't be made about X.

Agreed. While the Web needs a way to handle stateful transactions,
such "session" capabilities must be added with *great* care.

Sessions are an optimization, and the optimizations suitable for
turning the Web into a global distributed software system are
different from those suitable for implementing a desktop UIMS. In
particular, because the Web has a larger client/server ratio than
your typical UIMS, the advantages of maintaining state on the client
side instead of the server increase in the Web setting.
