There's an GSoC project that may be of interest to folks on this list. It's aim is to add Gmail/sup like features to the Plan 9 mail system called upas.
This might end up creating something an awful lot like Sup the Service Not identical for sure, but there is at least some overlap in terms of aims and ideas. Most services on Plan 9 are implemented as synthetic file systems. The synthetic filesystem that represents email on Plan 9 is known as upas. upas provides a filesytem view of mail boxes regardless of their backend storage medium (eg, POP, IMAP, etc) which provides a nice clean separation between the code that you use to do useful things to your mail and the code that deals with the mail store itself. To quote the man page: The mailbox itself becomes a directory under /mail/fs. Each message in the mailbox becomes a numbered directory in the mailbox directory, and each attachment becomes a numbered directory in the message directory. Since an attachment may itself be a mail message, this structure can recurse ad nauseam. Each message and attachment directory contains the files: body the message minus the RFC822 style headers cc the address(es) from the CC: header date the date in the message, or if none, the time of delivery digest an SHA1 digest of the message contents subject the contents of the subject line . . etc . Here's the manpage for upas: http://plan9.bell-labs.com/magic/man2html/4/upasfs The GSoC project: http://socghop.appspot.com/student_project/show/google/gsoc2009/plan9/t124024225207 There's a ton of interesting and powerful stuff in Plan 9. I'm hoping this will provide some useful ideas for Sup the Service. Jon -- Jon M.
