Ultimate mobile .htaccess redirect

I've got a decent working solution to mobile/desktop redirection in place using .htaccess code below, but there are a few more enhancements that could really make it ultimate if anyone can help.

Directory setup:

Cookie enabled links:

Current .htaccess file:

RewriteEngine on

# Check if this is the desktop to mobile query string
RewriteCond %{QUERY_STRING} (^|&)m=1(&|$)

# Set a cookie, and skip the next 2 rules 
RewriteRule ^ - [CO=mredir:1:%{HTTP_HOST},S=2]

# Check if this is the mobile to desktop query string
RewriteCond %{QUERY_STRING} (^|&)m=0(&|$)

# Set a cookie, and skip the next rule
RewriteRule ^ - [CO=mredir:0:%{HTTP_HOST},S]

RewriteCond %{HTTP_USER_AGENT} "android|blackberry|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC]

# Check if we're not already on the mobile site
RewriteCond %{HTTP_HOST} !^m\.

# Can not read and write cookie in same request, must duplicate condition
RewriteCond %{QUERY_STRING} !(^|&)m=0(&|$) 

# Check to make sure we haven't set the cookie before
RewriteCond %{HTTP_COOKIE} !^.*mredir=0.*$ [NC]

RewriteRule ^(.*)$ http://m.website.com/ [L,R=302]

Things I'm looking to add:

  1. If we're going to desktop version, either from mobile or just a normal desktop visit, make sure it always adds www.
  2. For desktop to mobile redirection, direct to matching mobile page, but if it doesn't exist default to mobile home. (Example: if you visit website.com/chairs on your mobile it will try to redirect to m.website.com/chairs, but if it doesn't exist it will instead redirect to m.website.com. I think mapping would be something like ^(.*)$ http://m.website.com/$1, but not sure how to implement fallback to home page

Also, if anyone notices any errors or improvements in the current code would love to hear that as well!

RewriteRule ^(.*)$ http://m.website.com/ [L,R=302]

# 1.) Check if on desktop site and having www., if not redirect to www.website.com
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} !^m\. [NC]
RewriteRule ^(.*)$ http://www.website.com$1 [R=301,L]

2.) this cannot be done with mod_rewrite except "/chairs" is an existing file (and I guess it's not). So I would check it with your desired scripting language - e.g. in php:

if (!pageexists($_GET['page']) && $_SERVER['HTTP_HOST'] == 'm.website.com')
  header("Location: http://m.website.com/");

where pageexists() is a function you define to check if there is content for this page in mobile version.
