What are the downsides to this? The mount failing? anything else?

This is one of the options that I was exploring. If I can keep the  
user on the same node, then I can keep file-based sessions on that web  
server and everything will be peachy. Are there any downsides to this?

Are there any big websites that use file-based sessions or are they  
all database-drive with huge clusters? We are using a database for  
sessions currently but it cannot keep up and brings the site to it's  
knees.


The last option I was considering was storing the session in a cookie  
as an encrypted, serialized array. What are the groups thoughts on this?
