Wow, that brings back memories... Back in the '90s I had made an X Input Method that used vim -- essentially forked a gvim process on a temporary file and read the file upon termination. It was a nice learning experience, but not very useful. Besides textareas in browsers (the main use, where a number of other solutions currently exist), a fun demo was to use vi for changing formulas in a spreadsheet (I assume it must have been StarOffice back then).
