One thing that would be nice, that pretty much no webmail does, is to keep a stateful connection open all the time (or at least some of the time) instead of creating tons of short-lived connections that ask the same stuff over and over again. With a stateful connection you could basically run IDLE and wait for changes there instead of asking all the time "is there new mail?" "is there new mail now?" "what about now?".I've seen several messages on the list that seem to indicate some clients don't maintain the connection. It will be interesting to see what the implications of this. Not sure if it can be done from a HTTP connection as it is suppose to be stateless.
It doesn't have to rely on a stateful HTTP connection. You already most likely use some server-stored state based on cookies/whatever. So among that server state you could also keep the opened IMAP connection. I guess the main issue here is that it doesn't work all that nicely if the HTTP requests get redirected to different servers randomly.
