Of course it's an ancient idea, but that doesn't mean it's not a good
idea. Biff/comsat were local notification or notification via hostname.
Local notification of mail delivery is easy. All modern biff
replacements that I know of function by polling a mailbox (POP/IMAP)
every N seconds/minutes. This is not efficient/practical for a cell phone.
The closest thing to push mail as a semi-standard protocol is IMAP's
