I think Bron failed to put sufficiently large warning signs here :)
The difference between "in theory this would work" and the practice of
actually doing it are huge. Basically it works only if you are 100% sure
that only one side is ever being accessed at a time. eg. IMAP/POP/LMTP/etc.
If somehow you get an LTMP deliver to different ends, then one side will end
up overwriting the other.
In other words, DON'T DO THIS.
