Ohhh -- so CASCADED switches, eh? Now you say! :-)

That'd be a bit more work, since both uncommitted and committed commands 
would have to be sent, and sent in the right order, with a delay between 
them. The patch I sent just lets you control either a committed switch 
OR an uncommitted switch, not both. Changing it so that the -S arg takes 
an integer argument would let you send both commands, and then there'd 
need to be a way to specify the order of the switches. Pretty simple, 
but I'm out of time to play around with patches ATM.
