It's not a large installation.

It won't.

Possible. You may want to have a central file server which will
hold all user mailboxes. Mount it under /var/mail (or
/var/spool/mail, whatever your OS prefers) on all mail servers
and Exim will deliver mail there and pop3 daemon will read it
from there.

Then, either write the pop3 proxy or use load-ballancing
switches (which also support high availability).

This is yet another possibility. But it's probably better not to
divide users between servers, but make all servers equal.
