                The 32bit VMs are only limited to a 4GB max each - but they 
don't know nor care where the memory comes from.  It is the host OS that cares, 
which is why it needs to be x64 so you can stuff that puppy.

                                                This was another thing I was 
wondering.  If I go with a 64bit host OS, I can use much more RAM, but I wasn't 
sure if the RAM that's unaddressable by a 32bit OS would be available to the 
virtual OSes.  I suppose since VMWare is the  bridge between the physical 
memory and the guest OS, it's possible.  If so, NICE!!!

                                a 64 bit host with 32 bit guests is the way to 
go.  You will be able to run more 32bit vm's more efficiently. The host has 
overhead and VMWare, Xen, etc were written to take advantage of 64 bit 
hardware.  Plus, you can cram it full of RAM which is where you will really see 
things perk up.

using the 64-bit cpu for 32bit apps/os'es
and so forth is no biggy. In fact, in a lot of cases, having that 
dual/quad core cpu will make life so much better! :-)  I experimented
with XP64 for about a week and uninstalled it. It didn't like my sound
card, and I wasn't having that! lol!!! :-)  64bit computing would 
probably be great, except for a few minor annoyances, like the lack of
drivers and the lack of 64bit programs to actually run! :-O  As you know,
max out on the memory!
