Deliver Shares Messages and Files Between Your Macs and iPhones
(or Other iDevices) Almost Instantly  OS X and iOS: Deliver does
what the name suggests—it delivers messages and files from one
Mac or iDevice to another over the local network. It does this
with absolutely no configuration and it is super fast. All you
have to do is download, install, and launch the app on any
computer or device on your local network and you'll be ready to
go.  When you launch the app, it'll teach you how to use it but
here's the gist. You'll see a little bubble icon. Click or tap
it (depending on the platform you're on) and it'll bring up a
list of other devices running Deliver. Choose the one you want
to send a file or message to and then click/tap the text button
(looks like a rectangle with three lines) or the plus button.
The text button is for sending a text message and the plus
button is for sending a file. Choose what you want and then
Deliver will transport it in an instant. I was surprised by how
fast a 4MB image made
