Would their be any potential side effects from a dynamic disk spanning drives running on different versions of VMFS?
Not for Windows, but if you have a mix of ESX 4 and 5 that could be confusing... so like weinstein says ESX 4 will be unable to have direct access to VMFS-5 datastores.. but Windows will be fine, it's a Datastore, Windows doesn't care only the VM version cares.. I believe only VM's versions 8 and up can see VMFS-5.
