I think the main issue is always money, so the OP idea is really a non-starter. I'm surprised at the problems some of the posters seem to have with camping and warmshowers. I've had so many great experiences, especially in the small, Midwestern towns. In the West, I generally have no problem with stealth camping on BLM/National Forest land. I would like to second the plea for more "hiker/biker" accommodations in all campgrounds and a little flexibility with RV resorts as well. At RV places more than once the management has REFUSED my money--full fee, mind you, with hookups--because we---the horror!--had a tent. That just flat out sucks at the end of really hard day with a storm coming in--the bastards. Once, on rolling into Folsom Lake campground near Sacramento, my wife and I were thoroughly worked, having cranked 70 miles on a loaded tandem trike WITH a dog and trailer, end of the day, all motels booked (we had checked), and the pea-brained idiot working the kiosk just said, "Sorry, we're full." There is TONS of empty space that would not impinge on any campers all over that place, but the jerks had NO flexibility for two totally exhausted cyclists. We couldn't just pick up and hammer another 10+ miles. We were done. I wanted to do violence, let me tell you. We pedaled around the campground, found a nice looking group, and asked if we could share their site, paid half, and took some of the scouts who were in the group for a ride on the tandem in the morning--great time, problem solved. May small-minded bureaucrats rot in hell.
