Allow read-only sync

[glasser]

I'd like to use org-sync to maintain an org file syncing issues from a shared repository into an org mode buffer, but I don't ever want org-sync to update GitHub directly. Would you support an option to do a one-way sync? Or maybe a different top-level command that I'd use instead of M-x org-sync?

You need a separated setup with "pull" and "push" to Github? It is a good idea!

We could have another entry point for read-only functionality, say org-sync-import-read-only. Another option would be to have some property in the document. I could actually see both being useful, like if you use org-sync-import-read-only first, it will set a property in the document and if you subsequently do org-sync it will refuse to push as it sees the property. That would avoid accidentally pushing updates.

I would like to have this as well. A separate fetch/pull for tickets. I don't trust any software enough to put stuff into production issue trackers :D (I'm already using org-jira in a read-only way and I'm looking for something for github).
