+I have now tried mu4e and I don't like it nearly as much as notmuch, so\r
+I'm sticking with this and aim to help out where notmuch falls short on\r
+tag syncing between machines :-)\r
+\r
+David Mazieres <dm-list-email-notmuch@scs.stanford.edu> writes:\r
+> the complexity of altering files is not worth it.\r
+\r
+I agree. Immutability is a great thing. I like the proposed approach of\r
+having a single "archive" Maildir folder (which notmuch really uses),\r
+and then copying files into other folders to flag them as having a tag\r
+or not (but these folders are not indexed by notmuch, avoiding\r
+duplication problems).\r
+\r
+It sounds like Gmail would play well with this setup and I assume most\r
+IMAP servers will be smart enough to treat these as references to the\r
+same immutable message. There is a potential persistent memory cost on\r
+the client side due to the excessive copying, but somebody pointed out\r
+that hard links would solve the problem locally. That just means the\r
+IMAP sync applications just need to be a little smarter about how they\r
+communicate with the server. I'm not averse to writing a tailored IMAP\r
+syncing app, although it would be in a real language like Scala or\r
+Haskell :-P Some sick part of me is also bizarrely intrigued by writing\r
+it in elisp.\r
+\r
+I am going on an extended holiday very shortly, but I hope one of you\r
+does some more feasibility testing on this during that time: when I\r
+return I will most likely help out with contributions.\r
+\r
+\r
+> what you want is an imap server built on top of the notmuch library\r
+\r
+That wouldn't appeal to me: I want to continue using my gmail account as\r
+it is well integrated with a variety of other services, gratis and the\r
+spam filtering is incredibly strong.\r
