[wp-hackers] Edit Template Tags with Plugin

I think this would be really tricky. Any solution would have to  
involved output buffering because those template files virtually  
always include script (unless you wanted to filter script). The  
functions you mentioned all have a do_action hook, so it might be  
possible to hook into that, turn on output buffering, load the files,  
process the buffer, and then output it. After the hook, WordPress will  
still try to load the files, but it uses a require_once, so that  
probably won't do anything.

Out of curiosity, what would this be used for?
