Several of us are looking at the GA144 for potential applications. I am 
having an interesting time looking at the analogue inputs for the device at 
present (especially using the widest range of input mV possible while 
maintaining some sensible accuracy over the range - the polynomial 
correction factors are going to be most interesting). 

I am sure that the GA144 could probably do a better version of this device; 
<http://www.gabotronics.com/development-boards/xmega-xprotolab.htm>. Maybe 
it won't have as many inputs as the model shown but could probably do a 
direct on-the fly representation of the signals and maybe even some data 
logging for good measure. Even if a separate USB interface or PHY is used it 
would not detract from the application brilliance.

I think it just takes some good ideas to be brought to the device and 
implemented. I hope all those currently playing will, eventually, put in 
some of the input to the Application Notes themselves. I will for that which 
does not have NDA restrictions.
