Fun with Delphi XE6 App tethering and barcodes

Updated: Removed broken GDrive links, now linking to old GitHub repo.

One of the new key features in XE6 is what Embarcadero has chosen to call App Tethering components - the only problem I initially had with the name was that it implied that mobile had to be involved in some way - which is not the case. You can make a windows service that is a "receiver" from a desktop application running on the same sub-net.

An example could be POS systems, running on various devices talking to the same receiver - without bothering about implementing multiple communications protocols - these components all wraps this up nicely.

I wanted to give these new component a try, by making a very simple barcode scanner using my phone as the barcode scanner and then have the receiver send the barcode to whatever application was active.

A word of warning: this is a prof of concept - not ready for production or deployment - you need to do some work yourself to make it fit your needs. I have tried to use as little code as possible - leaving out all exception handling :-).
