Hello Dan - I absolutely love this model and concept! (so many potential advantages and possibilities exist). Have you considered working with external partners in these cities to help support/fund a portion of the expense? In the grad program where I teach, we partner with external organizations to have our students work on real-world problems (i.e. the organization gets free consulting from our students and the student gets great experience/exposure). Perhaps such collaborations could lead to partnering organizations paying a nominal fee that could be used to help support the costs for your learners? Just a thought.....also, there is an organization in the Netherlands (called "Seats to Meet") that you might be interested in exploring along these lines as well. Again, VERY cool project idea!
