Hi Steve,

Sorry to take so long to get back to you. We are currently evaluating 
whether getting VDO accepted into  the main linux kernel will require 32 
bit support. It will be very difficult to make VDO work on such systems, 
and much more difficult if not impossible for it to perform well. If at 
all possible, we hope to only support 64 bit systems.
