Makes sense. I won't need to play Windows stuff on the backend, and the 
Revo frontend will be 32-bits.

Once I get the Revo up and running, the 64-bit machine will be a backend 

I've never had trouble getting 32-bit libs to work on a 64-bit machine, 
perhaps the apps I have run have been better behaved than some others. 
I've not had to resort to a 32-bit chroot.

Thanks for the insights.
