Some time ago I wrote some lines on how to support not only local
but also remote clients. The bottom line is to treat applications
available on the Internet similar to documents and thus access them
via a to-be-defined URI. Embedding graphical applications inside
graphical WWW browsers can be done in principle, at least for X11
with the new Fresco toolkit available with the now very soon to be
released X11R6. However, security is still an issue to think about

My suggestions are available as
Perhaps I'll get some feedback from you?
