These are all good questions, which I don't think anyone here will be able to answer because if you're using X1, you're using Windows.
If the Mac version of virtulisation is anything like VMware for Windows, it is possible to expose the underlying operating system (i.e. the Mac's) files to the guest VM (the VM running Windows) so I'm sure X1 could see the files. But how well it'd index them? If they're in standard format then I'm sure fine, but I don't think it'd index anything Mac specific.
As I've never used a Mac I can't tell you how Spotlight compares. I get the impression though that Spotlight is a lot like Locate32 for Windows, great at Filename searches but not much else. But, never used it so don't know.
You should give it a try and report back your findings!
