Wireless data transfer from/to device

Is it possible to send and/or retrieve data to my device via wifi? Maybe via a companion app and adb or some other trick? Or via a hidden debug mode on the device or whatever...

Usage

I'd like to push a prg file to my device (sideload it) and to retrieve the crash log afterwards - but all this should be done without the need of a usb cable connection.

Addtionally it would be nice to access the device wirelessly for pushing media to it as well e.g. and similar...

Sidenote

Of course the device and my computer are using the same WiFi and the device is set up to use this WiFi as well.
