That is what I am seeing, yep.

Thanks a lot for the hints.  I think you are suggesting something like:

function nevow_appendNode(node, what) {
    var oldnode = document.getElementById(node);
    oldnode.innerHTML += what;
}

This works just dandy on Firefox, and not at all on IE.  I get, "Error: 
unknown runtime error."  But oh well, it's a start.  Probably I'll look into 
hacking nevow_glue.js to use MochiKit.DOM.  Or...

...should I be looking into this?  I wasn't aware of nevow.athena, but I see 
I've got it installed.  I don't have any legacy code to worry about, should I 
just skip nevow.livepage completely?  Would you trust 0.6.0 not to put its 
elbows on the table or vomit on the Japanese?  I don't really want to hack up 
javascript if I can avoid it.
