Cool idea for a portable digital control surface

Being new to this, I'm not sure if Sonar can do this or not.  Seems cool though. At least in my humble opinion.
Imagine having the ability to work in a client server type sitation with Sonar.  You have Sonar installed on your computer. It has all it's normal functionality. Mouse, keyboard, existing touch functionality... Everything it does today, it still does.
 
Now, lets say you have a lenovo, dell, (what ever brand) touch screen device. Wouldn't it be cool if you could install a digital version of a control workspace?  Imagine having the V-Studio 700 on your touch device.  Now, imagine if it was wireless and you could walk around the room with it. You could control Sonar from 20 feet away, maybe you need to walk over to the guitarist and see what he's hearing or what ever... Or maybe you just wanted to be able to step back further from your monitors and be able to tweak FX or volumes...
 
I dunno... From my humble opinion, I think it would be really slick.

It's not imposing. The idea here would be no more imposing than someone having a physical control surface. You can use it, nor not use it. It would simply be an extra feature.  Also, some people may not want to use a small touch device to run sonar for what ever reason that may be.
 
Ok, take sonar completely out of the picture.  Just imagine some 3rd party company creating a software app that was a touch screen control surface that you install on your device that could control any DAW.  Sonar, Reaper, Pro Tools, ect...   Maybe that's a better way to look at it.
 
 

I don't think splashtop can do what I'm talking about.  Splashtop looks more like a way to get access to your files and what not.  Or to remote into your computer.  That is a different situation than what I'm talking about.

If it's the remote function you want, will TouchDAW do it?  Have't used it myself yet.

Have you tried the App "TouchDAW"?

I will say this Red. At least this is a lot more interesting thread then the X2 vs Cubase thread. 

I agree that a phone is too small for most things, but an iPad is getting there.

Won't a larger tablet (if they exist) also work ?

Isn't that more or less what you were asking for, Rick ?

I've been running TouchDaw on my Kindle Fire HD.  A 9"-hires display is plenty of room even for the fat-fingered user.  The Kindle has a huge wireless access range. I could probably control SONAR from the street outside.

This is actually the first time I ever used a control surface and I do like it. 
 
You need to download and run a virtual MIDI port application on your studio PC.  I chose rptMIDI.  When I start a session it takes about 30 seconds to run rptMIDI and set up TouchDaw.  I also set the Kindle to "not sleep".  The operation of the controls in TouchDaw is smooth with no noticeable lag. 
 
I'm just getting used to operating on 8 tracks at a time.  Maybe I will re-organize my projects to work better with "8-track" sets.
 
I think they also have a free version you can try.

That way i dont have to have a control surface capability. the screen emulation provided lets me operate the software like i was there.
