The typical HN answer is "yes, and start a new company", but I think there's a lot to be said for "yes, and work remotely for the company you're at." It's probably not too difficult to swing, you'll get to enjoy life instead of panicking at your struggling new venture in a new town, and you'll be able to take advantage of all the experience you've gathered at current company.
Honestly, I don't know if I'm giving you advice or myself.
