I guess this is not what you are after, but have you considered mapping
keys in vi? E.g. something like
:map = 1GO^[!!date;whoami;hostname^M1G3J:w^M
Now, pressing "=" in command mode adds a line at the top of the file
with current date, user and host, then saves the file. You could be
creative with !command, write your own script or c-program to generate
