We now have CVS and Google. They make it much better than before..

Depends who you talk to I guess.. I would question how much call
there is for traditional "servers" and traditional "clients". 

It's quite insulting for Small/Medium businesses to always be lumped with
the "cheap clients", and the big business be fed an "expensive
server". That's only to impress the boss of the "enterprise". I personally
think people in the smaller businesses need to be given more respect.

These days they are often the clever ones who don't want to put up
with all the crap that goes along with working for a big company.

I guess it would be. Off the shelf is usually the easiest.

So many of questions...  how to answer..

I think though the best answer is to just try them out for yourself.

Our software "rules" aren't really rules, they are conventions. Everybody
is free for themselves to try out different or new paradigms if they think 
that it might help.

Quite possibly.

Yes.

Yes.

Yes.

Possibly. Just install more RAM and a faster hard-disk. :-)

Yes.

Don't know. I've never used XAML.
