Nice! Now that got MY attention.

I suggested that a couple of years ago somewhere, possibly in Guitarix forums. 
The ability to go from schematic (to Faust) to actual real finished plugin 
 would be fun and educational in many cases. Other cases not so helpful 
 (say, digital delay best done with code).

Does this mean the gSchem family can use Faust/Guitarix tube models ? 

Interesting, thinking also toward the future to high-samplerate plugins 
 and hardware. Software Defined Radio for example.
Someone asked recently on Jack ML about high Jack sample rates (in MHz).

I think pretty good actually, in this case.
Faust and Guitarix have some nice sounding tubes.
Guitarix seems to have a solid foundation by using Faust.

The Guitarix Head's sound is awesome Hermann.

Have you ever thought of simulating the Head right down to
 adjustable power supply (Van Halen's Vari-AC Brown-Sound), 
 power supply ripple (simulated hum), and sag (commonly called 
 slow-gear effect)?
