That's the idea.  David just sent me his stuff a week or so ago, and I've 
been pretty busy, so I haven't had a chance to do much with it, yet.

I'll add the splitting of bindings from the .rb files.  I've thought about 
it a bunch but haven't done it because I'm lazy.  :)  Off the top of my 
head, I'll probably use .bnd for a bindings file unless someone has a better 
suggestion.  So:

Index.html
Index.iwa
Index.bnd

And yes, in fact, you don't need to wrap ruby code in the <% %> in a .rb 
file.  That was a legacy thing that I got rid of quite a while ago.  If one 
does that, it still works, so the old stuff still works without changes, but 
there is no need to do it now unless one is putting the code section and the 
html section into the same file.

Index.iwa
-----
import 'Header'
import 'Footer'

class Index < Iowa::Component

# blah blah blah

end

# Bindings are still in the .rb file, mostly because of laziness.
<?
  fooList {
    item = foo
    list = foos
  }
?>

For vim, I just added .iwa to the list of extensions that the ruby syntax 
highliting module recognizes.


Hope that helps,
