That's a different thing, though. You don't edit the data in a text editor interactively, do you? I would do any interactive editing with a local editor and then fire off remote processes to operate on the data.

It's funny because my reasons against using a text editor remotely are exactly the same: to make the development loop tighter. I am very upset by latency and always try to remove it where possible. I think this is the kind of thing where we'd need to look over each other's shoulders to understand our respective workflows.
