I was wondering, does anyone have experience using Vim across multiple monitors, with each instance sharing the buffers? Perhaps with Vim running as a server or something. Nothing really came up in the googling I have been doing.
To clarify, I would have to be running two Vim instances as my monitors are oriented differently - stretching them or using screen does not work.
Nope, there is no shared buffers in vim, it was designed to work like that and will always work like that.
If you only have specific task, such as yanking between two different buffers, you can get away with that by using little hacks, like using the OS's clipboard or doing some arcane stuff with temporary files...
