LayoutProxy and mod_rewrite [P]

OK, so after turning off -DDEBUG I have been making good progress in 
getting mod_layout ready to use on our sites.  Today, I ran into two 
obstacles.  One is surmountable, but I haven't figured out the other one 
yet:

1) mod_layout does not like to cooperate with mod_gzip.  We have used 
mod_gzip for quite some time on our static and dynamic content to save 
on bandwidth.  I turned it off for testing and found that the problem we 
were experiencing (no page data received by the browser) went away.

2) mod_layout does not merge the header into pages handled by the 
reverse proxy module.  We have a multi-tier setup here, so requests for 
dynamic content are passed off to hidden application servers via rewrite 
rules like this:

RewriteRule ^(/foo/bar/.*php.*) http://coolappserver.us.com/$1 [P]

Which is supposed to be the equivalent of ProxyPass.  The only problem 
is, the header doesn't show up.  I tried adding the 'LayoutProxy On' 
directive, but that didn't seem to make a difference.  Has anyone else 
gotten this to work?  If I can't get the front-end web servers to add 
the header, I will have to install mod_layout on all of our app servers, 
which will increase my consumption of aspirin.  I'd like to avoid that.
