Have you tried

	tee stdin | vi something | tee stdout

It captures the I/O despite it being raw - and vi doesn't seem
to mind a bit i.e. you can't tell the tees are there!

It seems that vi's ioctl calls to get into raw mode affect 
the reads and writes of tee!

The shell checks whether its reading from a tty and omits
the PS1 prompts.

        tee stdin | sh | tee stdout

is rather difficult to use.
