I have not looked into the new verbatim code yet, but I have been thinking 
about a similar interface for a new module that uses external programs for 
syntax highlighting (sort of a superset of t-vim that will allow one to 
use other programs like pgyments, etc.).

Why are you using a C prefix for all environments? Isn't it better to use 
a syntax like this:

\startsetups[verbatim:C]
\definestartstop[SnippetName][color=...,style=...]
\definestartstop[string][color=...,style=...]
....
\stopsetups

and then pass setups=verbatim:C to an appropriate \setup... command. That 
will make it easy to share the same syntax highlighting between different 
languages.
