Thanks cj. Spot on about IP matching. Took a little while to figure out how to get the client IP on Heroku, write up here: http://catapulty.tumblr.com/post/8303

About browser <--> iPhone, it'll work if your phone has the same IP as your browser, this might happen if your phone is using your home WiFi. Getting the bookmarklets into your phone might be a bit trickier and require some manual editing of bookmarks. Would be good to come up with a nice way of getting the bookmarklets onto phones. To avoid the requirement of same IPs, I guess that'd require a way to create and identify an account on Catapulty. If that looks like it'd be useful I'll add that in.
