Would a wireless volume knob for home theaters be worth it?


I've been looking around and cannot find any remote control that has a volume knob on it.  Would having a volume knob that can control my home theater volume be better to using volume buttons?  Or would the cost not be worth it?

@sfseay very interesting, I wasn't aware of this brand.

Is the remote volume knob better than using a traditional button remote?
Much better to me to have the volume knob.  SST Audio was started by James Bongiorno who is a very well respected audio designer and engineer.

The SST Ambrosia 2000 Second Gen preamp is the best purchase I have made in the last five years.  Stellar pre amp.

Background on Mr. Bongiorno:
The Ambrosia 2000 may not look like audio jewelry and some might find it not to their taste but to me it sounds fantastic and represents one man’s passion. 50 pounds of sonic bliss!

Some of James Bongiorno’s early designs and his last achievements were:

It's a very cool unit, but way out of my price range.
I'm mostly interested in the remote itself, I've never seen a remote like that in any other audio product.  I'm wondering why they aren't more popular.
