There's a dev branch for maildir sync, but I haven't tried it out: https://github.com/sup-heliotrope/sup/tree/maildir-sync

I agree that this limitation makes it really hard to fit sup into a workflow that includes multiple workstations and phones/tablets. Hopefully they get that sorted.

I've been running maildir-label-syncing Sup for a while. It works great, but you need the master Sup client to be running for new email to get sorted. http://blog.ezyang.com/2012/12/maildir-synchronizing-sup/
