There's an RFC for that... http://tools.ietf.org/html/rfc2223 http://tools.ietf.org/html/rfc2223 There's really nothing at all stopping intelligent people getting together and "fixing" IMAP, rather than building a compatibility bridge between siloed data gatherer A and reticent data hoarder B. I personally have zero problems with IMAP4. I run my own server. You could too... In fact if you and 10 friends want to each pay $2.00/month, you could rent and share a 48GB Linode - setup your own IMAP server with CalDav and whatever else. All secured with ssh public key only access and a free SSL cert from startssl. So you only get 4GB of storage space each... I wouldn't see that as much of show stopper for me or most people I know.
