This is just great. I have using the experimental versions of this for 
ages. And I think that this is what is in Ubuntu Linux.

For me Debian/Ubuntu with PHP5 is so easy to set up a site. I think the 
only thing that is missing from Debian for a PHP set up is an opcache. I 
usually need to compile APC from PECL.

I would love to use eAccelerator. But it doesn't really like PHP5 
objects very much. I know that it crashes on CiviCRM.

This will be great to see. For all of my development I use PHP5.

I think that this would be a good idea. Being able to use the latest and 
greatest versions of PHP will mean that we can start to use the new and 
better functions and improve how we do things.
