I have a client doing that, although I'm not sure that they'd want to be
used as a case study.  You will need Apache2, as you need to reverse
proxy both HTTP and HTTPS (ie, HTTP into HTTP, and HTTPS into HTTPS).  
You'll also need to ensure that the domain that the Exchange webmail 
considers itself to be is the one that is used by the proxy externally
and to talk to the Exchange webmail, otherwise you'll most likely end up
in a redirect loop.

Aside from that it does work, give or take the usual issues of an
application proxy (eg, external source IP addresses are hidden from
Exchange).

Were I doing it for a less Microsoft centric client I might well have
suggested SquirrelMail + IMAP to them.  But for a Microsoft shop there
are other advantages in the Exchange webmail access.
