Why was it impractical? Remote access to a single IMAP server in one 
location ought to be possible. We spend extended periods in several 
countries. I keep all my email (collected via fetchmail/exim) on an IMAP 
server (dovecot) at home and it's never been a problem to access it 
remotely from different countries and different devices.

If you are using plain maildir, then I think you could just use rsync to 
synchronise the two sets of folders and files. I guess you would need to 
exclude from the rsync operation the dovecot-specific files (indexes and 
so forth) and allow dovecot to update these itself to reflect the new 
state of each set of stored messages.
