Hello, Beatbuddyes! I live in Brazil and here the economy is crap, especially in my pocket! A Beatbuddy arrives here for about six hundred dollars, because of the fees, taxes and shipping.
I loved the stompbox Beatbuddy and the whole concept behind the idea!
Because of this, I created my own solution using Beatbuddy Manager as a rhythm machine itself!
I adapted a mouse to work as a footswitch and works perfectly.
My suggestion would be that you develop a mobile app that used a footswitch connection in P2 (headphones) as a trigger.
It would be a success! I would pay a few bucks for it!
Congratulations on the excellent product. Peace and good luck!
