I purchased TouchDAW and was working with it over the weekend. It has a cool, semi-documented feature that allows you to "misuse" it as a wired-to-wireless MIDI router. With an OTG adapter and a class-compliant USB MIDI device (I used an ION mini MIDI keyboard) you can plug the MIDI device into your Droid device and route the USB MIDI IN to wireless MIDI out. I did have to provide external power for the keyboard as my tablet can't power it but I could probably rig up a small battery to be completely wireless.
Here's how to do this (assuming you already have a working wireless config with TouchDAW):
1) connect your class-compliant MIDI USB device to your Droid device with an OTG (host-mode) adapter. This should cause an OS pop-up to appear.
2) select TouchDaw from the pop-up. This assures that no other app grabs the USB device.
3) Launch TouchDAW and make sure the (General Settings/MIDI) MIDI RELAY option is checked
4) TouchDAW allows for 2 MIDI connections, one for the TouchDAW control surface and one for MIDI Utils. For one of them, set the MIDI connection to a working wireless (rtp/multicast/bluetooth) MIDI connection and the other to USB from your wired device.
That's it! Note that the function (TouchDAW or MIDI Utils) you set to use USB will not work as MIDI is now being generated my your USB-connected h/w. I have hotten this to work with rtp and multicast connections. I hope it works via bluetooth but I haven't been able to get that type of connection working yet as my laptops can't seem to connect using the TouchDAW Thru PC client.
After all my playing with wired-to-wireless MIDI, I barely had time to try TouchDAW as a control surface to X2. When I did get it connected, I found while the faders worked, the transport controls didn't. Not only didn't they work, but it seemed like TouchDaw was continually sending out a stop/pause message and I couldn't even start playback from the PC without it stopping immediately as long as the MACKIE-1 control surface was active.
I see some here mention having transport issues yet others seem to have it working?
Oh, one other thing I've learned: If you use rtpMIDI and Bonjour, turn the services off from SERVICES.MSC whe you don't need them. I found that on my laptop DAW, rtpMIDI will occasionally hog the CPU when the PC resumes out of sleep mode.

UPDATE: Was able to get a successful connection via Bluetooth. Best $5 I ever spent...
