There is a problem with this, you cannot do getHTML on a LoadPanel in
Netscape 4. The DynAPI is cheating in Netscape 4 because when you setHTML it
keeps a copy of the HTML that can be returned by getHTML. However using the
LoadPanel doesn't call setHTML.

A perhaps more suitable solution would be to use a frameset, and return the
response in a textarea wrapper (like what you said in number 2, but using a
frame not a loadpanel). NS4 can get the contents of a textarea.
