 Be carefull though, all users sharing the same cache makes it dangerous to use APC's object cache as all sites can access and modify each others cache. The only way around this would be to run a seperate intance of php-fpm for each account multiple config files with 0 pool per config file. I would be interested to know how http://cpxstack.sysally.net get's around letting users configure their URL rewrites... Edit : I've just seen their video that shows a user choosing their nginx rules, very nice indeed ! :) Not sure how they manage to have both apache and nginx on the same port, but it seems the video seems to show exactly how it should be done. Could cPanel look into working with them to get it checked by cPanel and implemented officialy by cPanel ?
