[TYPO3] Options for hosting multiple sites - revisited ...

[Kathy Wheeler]

I've searched the archives and found a question almost identical to  
mine, but no answers to it ... so I'll ask:

We need to roll out a multiple domain Typo3 installation - mostly  
small client sites. My server admin has asked how we are going to  
keep track of individual site disk usage for billing purposes.

 From what I've read the easiest way to handle multiple domains with  
Typo3 (letting Typo3 do the domain handling with the separate sites  
as different page trees on the one installation) will put everything  
in the one database. Is there any way, preferably one that could be  
automated, to
a) keep track of an individual domain/client's disk usage within the  
one database and
b) remove a client site (if the client moves away or goes out of  
business)?

I'm leaning towards the other alternative multiple domain option of  
one Typo3 source with multiple installs with their own databases,  
using the symlink to the source etc. A bit messier to set up, bigger  
overhead for each client install, but I think easier to admin.

I would appreciate advice on how others have handled disk space  
billing for multiple domains, and any other opinions on either  
multiple domain handling option.

Cheers,
