There is interest, but most want to join rather than create. Its a chicken and egg thing, they won't get involved until something is established. Don't count on many from my connections, at least not at first. That being said, my attempt was when "makerspace" and "hackerspace" were new words. Maybe now there will be a better response.
Right now I visit PS1 once or twice a year, and monitor the mailing list most every day. I also tried to visit Workshop 88 a couple times, but it seems well hidden; I monitor their mainiling list as well. I encounter folks from Chibots, PS1 and workshop 88 at events in about equal numbers. So while rare, the interested parties are fairly enthusiastic.
The most limiting factor is travel time. I would have to drive less than 20 minutes to make use of the physical space. Longer than that and I am limited to internet communication. However, email alone keeps me in contact with a large number of folks all over the world.
