[racket] compiling Racket to android and ios apps

Sounds like LambdaNative (which looks like it's based on Marc Feeley's 
nice Gambit implementation of Scheme) is worth looking into.  (Helping a 
LambdaNative approach for us is that there are viable ways to share a 
lot of app-specific source code between Racket and another Scheme 
descendant.)

Good to know that Clojure-Android is out there.  I don't want to move to 
Clojure at this time, but having people advancing a diversity ways to 
make apps for popular platforms helps to keep the ecosystem healthy and 
open for everyone.
