Installing serviio on a PC running windows XP but run from 7

Hello,
Great software by the way, I really like it. I am new to it and i Need a bit of help.
Background: I have a laptop running windows 7 32-bit. I first installed serviio on it and it worked finely (today) but then, while downloading some files, I ran out of memory. So I decided that I'll use an external hard drive. The problem is that it IS an external hard drive (USB connection only). So I decided that I am going to connect it to another PC that I have. I have a SONY Vaio PCV-RZ24G which is running windows XP and I connected my Western Digital My Book (1TB (WD10000H1U-00) to it. I am also sharing access to the external hard drive from the Sony Desktop. So from my laptop, I can see the drive and write to it. Both drives are NTFS.
Project: So this is what I am trying to accomplish if it's possible:
I would like to "run" serviio from my laptop (windows 7), while the hard drive remains connected to the PC desktop (windows XP). I am wondering how is this done? I have read about the NAS and all, but I honestly don't even know where to begin. Is there a step-by-step protocol on how to do that?
As a sidenote, I would also like to have my utorrent download to that same drive while operating it from my laptop...(but that may be for a different time & place) . So would someone be kind enough to help please? Thank you.
