Regarding (2) - I don't want to *reconsider* using Ms Outlook. That would be a step or two backwards from the Mozilla we use, which comes with fine IMAP support. The centralized-storage, universal-access model of IMAP is a very good reason to use it, with a good variety of clients available.
FWIW, we only have a small network, but UW IMAP has worked well.
I like your candy analogy. But it would be more correct to say:
You get the candy for free, but you if you share it with others, you have to leave the wrappers on so they don't get sticky fingers.
