Synchronization success stories?

[Brian Sniffen]

I'm thrilled by using notmuch to manage my mail.  Low-latency search is
very important to me.  But I use computers in a couple of
places---several of which are laptops.  Has anyone stories to share of
successful multi-computer notmuch sync, for a corpus of a
quarter-million messages or so?  

I've tried offlineimap---it (and my Exchange sever) get grouchy with
mailboxes of that size.  I tried keeping ~/Maildir/ in Google Drive; it
took weeks to do the initial sync and I gave up.

I'm trying bittorrent-sync now, with no obivous failures.
