Quite some of the metafun macros are generic but there are also a couple 
of extensions that work only with ConTeXt and some even only with 
ConTeXt mkiv (the luatex version). Of course I could make most generic 
but it's not worth the trouble and it would cripple further development.

However, you can make independent metafun graphics as follows. Make a 
file, say test.tex:

   metafun code

Then run

   context test.tex

and you will get a graphic that you can include in whatever tex macro 
package. So, you only need to know two context commands.
