Well, they work okay for one off events, but use case I have in mind is the 40 or so wineries in the county where I live; about half or more hire folks to come play music on a Saturday or Sunday.
If they'd all just subscribe to a service, then they wouldn't have to dicker with a bunch of musicians and have their tasting room GMs deal with booking folks.
The same thing could apply to all the little bars and restaurants here; they have a reoccuring need to hire talent, but they usually have some staff member who doesn't want to be doing it (and isn't getting paid much) buying talent, so it's a pain in the butt for musicians and the bars get inconsistent products.
But at that end of the market, the budgets are so small that it'd be tough to take much out to work as a service.
