+Looking forward to the export support! 
+
+Just curious (and I apologize in advance for any nightmares induced) did you consider the case of four files, A–D, where (content-wise) A=B and C=D and the change is to swap A/C and B/D? That'd potentially be an issue, since four files want to share two temporary names. Unless of course it's all only done with pairwise swaps.

+Hello,
+
+I want to use git-annex on a directory that also other persons, without git-annex use, i.e. modify, add and remove files to.
+
+What need I consider when doing that?
+
+ * Use indirect mode
+ * The the .git directory somewhere else?
+ * Be prepared that a ```git annex get``` can always bring up checksum problems because someone modified the file
+
+I assume git-annex checksums before pushing to the repo, so that I don't otherwrite someone elses changes.
+
+What else?
+
+Thanks!
