Yeah. Many Myth users have "secondary" machines that might not meet 
today's standards.

It's like in the TV business, we all figured that everyone had a color 
set, and so we didn't worry too much about how things would look in B+W, 
forgetting that a lot of monochrome sets still existed in bedrooms, 
kitchens, kid's rooms etc.

Backwards compatibility is always desirable. Perhaps there should be a 
stripped down version of Myth's frontend that would still support the 
latest database schema and other protocols, but would run on minimal 
hardware, even without the latest bells and whistles, but still usable 
with a reduced feature set.

Myth is not just a Living Room experience anymore.
