I don't know if I have fully understood all of the things, so sorry if
you see I didn't get the complete meaning of some part (sorry... not a
native English speaker).

Although I agree with you applications will get more "separated" from
the UI part, I don't quite see it as a whole server+UI thing, at least
as I understand that... Well I really had the (completely hypothetical)
idea of making a UI which the same code could be exported to desktop UI
(like GTK or whatever), web (with XML11) and console. So, in some way,
the implementation would be with the UI code, but that UI would be
accessible in the main three ways (desktop, web, and console).
For that idea... Mono has lots of things to offer, but I'm pretty much
concerned about the performance it can be achieved with Mono when
running on multicore architectures and the ease of the coding to get a
good performance.

Think that when I say desktop apps I refer to a whole bunch of typical
apps you can see in a desktop, not just one app I could have in mind
right now. Think of filemanagers, games, media players and that sort of
apps... And as I've just said to Richard A. O'Keefe, I don't know if
Erlang is also strong in those kind of developments (I don't know if any
of those apps need a lot of concurrency where Erlang could be superior
to C/C++/C#).

Sorry if I'm being a little pain in the neck making so many questions...

Thanks for everything.
Cheers.
