It seems this would be just removing a bunch of redundant code (like 
Michael said), and making few adaptations to the existing -i code.
One problem with -i <grab device> is when you want to use the default 
grab device. This could be accomplished by (some suggestions):
a) using the '-' character
b) making -grab mean -i <default device>.
