Well, you will need something like a server-side language to get the
widgets working. DPS(=Display PostScript) was capable to do server-side
widgets - but somehow DPS was lost deep in hell.
Today such a project will likely "die" in the flamewar "which language
should be used: JAVA, Perl, PostScript, TCL, bash(ouch!) etc. ..." ...
=:-)
This issue could be solved via a platform-independent bytecode
interpreter... but I still doubt that something like server-side widgets
will ever become popular - it's a radically different approach compared
to today's toolkits and people don't like to rewrite/invent the stuff
from scratch if the "old ways" still work.

First things which come in mind: How can I debug those widgets ? How can
I stop one widget from screwing up the whole server (e.g. grab CPU, grab
all memory) ?
