It's easy enough to load safe-tcl documents to be viewed/execd by
an external viewer. If it becomes popular, then browsers will be
built with this feature built in.
Something I would like to see is a method for external viewers
to communicate back to the browser. People talk about this from
time to time but I've yet to see anything substantive (perhaps
I missed it).
It could be done any number of ways, we just need to pick something
that works well and use it.
