Congratulations. I signed up for an account and played around a bit. I can certainly see myself using this pretty soon. As a couple of people mentioned, instruction creation is a pretty infrequent activity - so a pay per month pricing scheme may not work best. VerticalResponse.com comes to mind (not associated in any way; I don't even use them) - in a market where monthly fees are the norm, they have a pay as you go plan that's tied to distribution (numbers). On another minor point: maybe it's me, but the 'appliance' bit had me expecting a device; I was happy to see there was none.
