Can you have two seperate iTunes's on one computer?

Question

Okay, I have and love an iPod nano 4GB White English. I have Windows XP, and I have iTunes on it, but we do not have seperate User Accounts for some reason, we have individual folders. My iTunes is in my folder, our main music "jukebox" program is Windows Media Player, all but I use it.
I am thinking of getting my sister an iPod nano 1GB White English for Christmas (early to think, I no, but...). However, will she be able to have a SEPERATRE iTunes from mine (we each have our own songs, we do not share), if she puts in in her folder? Or no? Do you have to have seperate User Accounts? Please tell me.

You can choose the update option "automatically update selected playlists only" which would allow you to create a playlist specifically for each iPod and drag the tracks you want into it. If you tire of the list and want to change it, you just add or remove the songs you don't want. The ones you take out out remain in the library to be used by the other iPod. Make your playlist a Smart playlist and limit the size to just below the advertised capacity of your iPod Nano (around 1800MB for a 2G). Another way of course is to choose to "manually manage songs and playlists" and update the iPod manually. You can read more about playlists at these links:

For info:
The iPod offers three ways to transfer music from your computer. You can select one of the following update modes from the iPod Preferences menu in iTunes (Edit=>Preferences=>'iPod' tab):
1) Automatically update all songs and playlists. This is the default mode, in which your entire music library, including playlists, is automatically synced to your iPod. If the music library on your computer exceeds the iPod storage capacity, you are prompted to select a different update method.
2) Automatically update selected playlists only. With this option, iTunes automatically copies the playlists you have selected to the iPod when you connect it to the computer.
3) Manually manage songs and playlists. You can also choose to transfer music to the iPod manually. This allows you to drag and drop individual songs and playlists from iTunes to the iPod.
