Looking at this briefly, I discovered that the p9p version of acme  
doesn't make available body/addr/ctl/event of the current selected  
window.  So the straightforward "substitute 9p commands" fails.

What is the correct way for a script to discover the ID of the acme  
window it was run from?  I could trap the command in the plumber and  
add the id as a parameter, but that's rather intrusive.
