I've implemented this in my company and it is relatively easy. But we use
two relay servers (+ MX entries), to make the relay redundant (of course
exchange is not, but at least the relay :)

I did this with squid. The 3.0 version has a special feature called
"front_end_https", which is needed if the OWA doesn't use https (which is
ok, in the LAN).

Yes, it is absolutely feasible! But I wouldn't do it with apache.
In any case, don't forget regular updates of BOTH machines using windows
update and fou4s/YOU.
