There, when creating a new SCRIPT-tag and appending the rewritten 
functions (and destroying the old ones, of course) all this works in 
Mozilla. I guess the same solution should work with Internet Explorer as 
well, if I could only get a list of the functions in the page. 
Unfortunately, IE doesn't list functions when I run a for-in loop on the 
window-object.

Any suggestions?
