Sorry, that's a detail I somehow overlooked. Your ultimate intention is to replace a Vista laptop with an Apple MBP. Connecting the two is just a means to an end. Do I get it now?
Arth, if you do get rid of the old machine, be sure to hand it down to someone who can use it. Preferably after zeroing out the drive properly.
In that case, setting up a so-called ad hoc WiFi connection between the two is dead simple -- there are built in routines for that on both machines. For ~$20, the virtual NTFS software for Mac OS X I mentioned above will work to use your current external drive directly with the Mac until you can get a second one -- something you'll want to do anyway just for the sake of redundancy.
Ah, now I get what you were talking about with the sparseimage on an NTFS drive. Do you use this software yourself, and is it reliable?
I'm not sure that Time Machine will recognize a virtual drive, but it will recognize an HFS+ formatted drive from an image file. A drive image file is just a document written to look like a physical drive to the operating system. The standard format for Mac OS X image files has the name extension ".dmg". The name extension ".sparseimage" refers to a file that starts out small and expands in size as more is written to it, unlike most formats which take up somewhat more hard drive space than their stated capacity whether they contain anything or are just empty space.
Another strategy would be to make a fixed size dmg to reserve the space. In any case you need to give even a sparseimage a sensible maximum capacity to avoid headaches later on. Again, a good size for Time Machine, is very dependent on what you need to back up. If you keep your media manually backed up, for example, there's no need to have Time Machine manage it on the same drive.
