I came across this ngrok tool/service (https://ngrok.com/) while listening to the awesome Shared Instance podcast (http://sharedinstance.com/49). It looks like it would be very useful for web service testing through my security spidey sense is kicking up in terms of production use. There’s a free plan (https://ngrok.com/product#pricing) which would be perfect for temporary use.
PS: The Shared Instance podcast is 3 iOS developers from Ohio discussing development. It’s like an Ohio version of Mobile Couch (http://mobilecouch.co/) though I’m not sure of the Alex^2 / Sam mapping to Jelly / Ben.
