I've prepared next version of patch.
Now it supports:
1) Seamless subdomain (without redirects).
2) Default config files and read-me inside (requires manual modification)
3) Optional support for user-friendly folders names. Renaming of sites and users supported. All paths will be updated automatically.
4) Added default DNS template for GoolgeApps.
5) Management of php-fpm pools, now PHP environments are separated (suFPM)
6) Synced with trunk-30/1/2009
