Although I'm not familiar with Prototype, I echo your concern.  I asked this
very question at a demo I attended several months ago (given by Bruce Webster).
Unfortunately, the answer is NO (or, was 'no').  Apparently, NeXT sees IB as
a "prototyper" and "initial implementation generator" and NOT as an Interface
Modifier.  Perhaps I would not be so sensitive to this "lack of a neato
function", but I have seen a similar tool here at HP that DOES allow one to
modify the interface.  The basic idea with this tool is that you define
"callbacks" (functions) for events.  These functions are defined in #include
files which are not modified by the interface builder.  Unfortunately, the
NeXT IB requires you to modify the files it generates.  If you can figure out
some way to do these modifications in a "repeatable" way, great!  Good luck!
