I think you are going to have added cost as soon as you implement this: 
especially with a short lease time, your CF will wear out very soon.

But: is it possible to use an NFS mount for these kind of things? If you 
really need it you probably don't mind setting up another server w/ NFS 
(eh... am I the only geek with to many servers? :)). Or, is this too 
far-fetched?

Anyway, just a thought.
