Sounds more like your colleagues have lost faith in the project and you want to continue on with it. If that's the case then it may be time to find a J.O.B. and put this on the sideburner. If you have faith in it, have collected plenty of positive feedback, and have interested parties lined up to use it, then there's nothing wrong with going to earn a paycheck to take care of your basic needs first. It may take longer but it may also refocus you on the tasks at hand. That... or go get some angel funding. There are more incubators/angels than just PG. How about family? Friends? Though it really sounds like your cohorts have lost interest (since they don't seem to be out hustling for more funding and have told you you need to work without even ramen money).
