It's a fantastic idea, and one I'm sure we would all take up in a hurry, but I am not so sure that it actually works that way. The only way to find out is to ask though! And you ask if the price is to steep? Well something is only worth what you are prepared to pay for it. Even then you still don't know. Wait till the workshop is over- then ask the participants if they got what they paid for[
] Just my thoughts.
