This sort of hosting is basically no different than a typical 'shared host'. Why is there no 'heroku for PHP'? Oh... because those have been around for 8 years+

This sort of hosting is basically no different than a typical 'shared host'. Why is there no 'heroku for PHP'? Oh... because those have been around for 8 years+ and are called 'shared hosts with Apache/PH/MySQL'. I've looked around on a couple of hosts, 1and1 and I think he.net and found that it was quite possible to go looking around in other users accounts through the shell. I'll stick with VPSs and dedicated servers.
