Have you seen the blurb on WebRunner and Java (from Sun). The former
is a browser, and the latter is an OOPL similar to (but cleaner
than!!!) C++. Java is compiled into byte-codes, and has mechanisms for
dynamically loading libraries across the network. It is soon to be
released under conditions similar to Sun RPC I believe.
Also, by "componentware", what do you mean? Will it be based on
OpenDOC, OLE, COM, CORBA, or...
Fresco probably deserves a look as it works under both X11 and WIndows
NT.
