I don't want to nitpick, but POP and webmail are different. Neither
really provide proper distributed access to storage. Webmail provides
distributed access to a mail client, not to the storage, and POP is
really just retrieves and deletes, which isn't FS-like at all IMHO.

The idea that people have just dropped in IMAP as a replacement for or
in addition to these in existing systems would at least provide an
historical answer to my question though. :)
