Touchpanel xantech or hai?

[signaturefactory@xxxxxxxxxxxxxxxxxxxx]

I am finishing the design of our new home automation/audio/video
distribution system.  I am getting ready to purchase the following:

Omni Pro II controller for security, ha control
Xantech MRC88 audio/video distribution controllers

I am planning to purchase about 4 touchpanels mainly for ha interface.
I have been looking at the HAI Omnitouch or Xantech SPLCD64V.  Anyone
have a recommendation on either of these?  I like that the Xantech can
play video but truthfully do not expect to use the panels much at all
for video.

The one issue I have been running into is that I plan to run a computer
(to play stored mp3 files) into one of the audio inputs on the Xantech
and I am trying to figure out what the best way to allow easy selection
of playlists, etc.  I was planning on configuring the MRC88 keypads to
do this but it definitely will not be user friendly.  Neither the
Omnitouch or SPLCD64V allow web browsing, which would probably be
ideal.  Anyone have any ideas on this?
