Erel,
I have a rest server that I made that works on Windows and I know it is a bit more complicated.
I use the UDP broadcasting to create a way for the tablets find the server automatically and self configure.
It works most of the time. If in the same subnet. My windows program register itself on the windows firewall during setup.
It is nice to see the names of the devices, but the 3 level menu is not nice at alll. It helps with the names, but I suggest to have some kind of interface, toolbar, or even a combobox with the devices would be easier than going thru the menus.
Thanks!!!
