HI, has anyone looked into using a pi as a voice keyer?

I know it has no audio in but using a cheap USB sound card should enable it to be put in a box, add switches to select files to play and other siwtches to control delays/repeats etc.
Could make a voice keyer far cheaper than the MFJ one I have seen with the same functionality.
