Quota Support

[Steven Adams]

Hey,
        I was wondering if its possible to implant a quota system where i
can give a user just say access to 2 databases which is allowed to grow to
30Mb bewteen the two of them..

What i would really like is if its possible to make mysql use the disk quota
limits.. So i can give the uses say 50MB WebSpace on my server which will
iclude his mysql db

Thanks
/Steve
