I've been giving some thought on to how to replace DAFIF navigation data
now that it's going away. And I think the solution is a community of
pilots, software developers and others interested in aeronautical data
developing and maintaining data which can be shared by all interested
parties.

Wouldn't data from sources other than the government expose
participants to liability?

Why? The FAA has rules as to what is valid for primary navigation, and
"random **** you downloaded from the internet loaded into some piece of
freeware you downloaded from palmsource.com" isn't on the list. It's not
like people are going to be loading this data into a TSO'ed GPS.
