I will also note that the Floobits people seem incapable of posting about their vim plugin without downing vim, as if doing this were equally or more important than their product.
Floobits is also currently free and the plugins at least are open sourced. It takes a significant amount of time to develop this software- hopefully users will find the value we add commensurate with the investment on our part and we can make a business out of it.
Finally, we are left in a strange position with users on why the Vim plugin behaves so strangely. Ideally, users wouldn't have to change their behavior at all; everything would just magically work. Unfortunately, Vim is purposefully designed to make things like collaborative editing impossible (it has no event loop and async actions are impossible). Vim is by design a text editor and not an IDE. We should probably communicate the limitations of the platform better to end users.
