There is an application to modify a xterm on the flight, 'xtermcontrol',
which supports:

$ xtermcontrol --help

  --version                           print the version number and exit

I poked around a bit and it seems to work with just sending
ESC-sequences to STDOUT. One could dig into its source and check for
more details.
