I wasnt aware of a size limit of the sessions files. I will have to look 
that up.

This is a good point, but your not completely correct either. It simply 
takes the use of a share file location for the sessions files. So if you 
use nfs or whatever and in the php.ini dictate that the sesion files be 
kept on the share, then you can do load balancing just fine.

If people still feel that db sessions have some benefit, then I wont 
fight to remove it. It doesnt matter to me that much.
