Again storing BLOBs in the filesystem can cause problems in cluster 
scenarios. You then have the options of :

- sharing the filesystem using an NFS-like sharing system. You also need 
to setup to avoid single point of failure problems.
- replicating but this means that all the nodes will not immediately 
have coherent content.

Ok, I'm curious to see what it will look like :)
