32 vs 64 bit

[Lance Reed]

Apologizes if this topic has already be covered....

Is there a general consensus about building a MogileFS setup and if the 
main storage nodes should be 64 bit or not.
I am specifically planning to build a large setup that will initially 
have 32 bit clients connecting to the storage setup, however these nodes 
will eventually be transitioned to 64 bit nodes.  Note sure if this is 
an issue using MogileFS.  In some distributed FS setups, this is a major 
concern.

Thanks in advance for any details.


Cheers,

Lance
