webhosting with php/mysql and disk quota

Hello all, is it possible to do the following thing with php/mysql? 1. user registers 2. upon clicking the "submit" button a php script creates a mysql DB with a unique name ( So far so good, till there I have no prob) 3. the specific user gets SELCT INSERT UPDATE rights for his database only. 4. Mysql quota is set to 10MB 5. user directory with write permission only by the specific user gets created under the www directory. 6. Syncronization of Disk quota and mysql quota e.g. 9MB pictures in the user directory, means 1MB left for mysql or the oposite 9MB mysql data, 1mb free in the user directory. This whole thing must run on its own without someone to create the accounts thanks in advance Vassilis -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
