Thanks for this. Since it's going to be registered as an issue I thought
I would provide some reasons for this.

+ I am trying to protect my data from hard disk failure - having 10 files
  all on the same HD doesn't achieve this.
+ I am trying to protect my data from site failure - even if I have 10 
  storage nodes in my flat (which is unlikely anyway) I still want my data
  to survive if my flat burns down.
+ I am thinking of using Tahoe with maybe 2 parts requiring only 1 part to
  make the file. I need to know that one of these parts went onto my server
  and another on a server in a relatives house.

I hope this helps for the issue. (Where I work we have to provide a business
Case for absolutly everything)
