Is it possible to two way sync a post type between multiple sites on a multisite install? For example if someone makes a change to an entry under post type "inventory" on Site A how can I make that reflect on Site B automatically and vice versa?
I am thinking that there are two main possible way of doing this, neither of which I'm sure can easily be done.
1) A plugin hooks into the edit_post so when a change is made the plugin edits the sister entry in the other blog's database table.
2) Anytime Site B views or edits an "inventory" post type it is reading it from Site A's database table.
