I have gotten it to work with mixed results using wine and iTunes 10+. Its hit or miss, at this point.
The Home Sharing feature in iTunes 9 will work with Macs or Windows and between Macs and Windows. Ensure that iTunes is running on all sharing computers and that you are logged into the same iTunes account on each computer.
You don't. Use rhytmbox instead. If you NEED itunes you can install it through wine (see link). It got a bronze rating, so there might be some issues. It may or may not run. See second link for details.
It is possible on music sharing sites. Your music profile is automatically updated on such sites when ever you upload, listen and share itunes.
There is not, and never has been, a version of iTunes for Windows ME.
You can go on itunes, you tube and a legal music sharing website!
Home Sharing is part of the iTunes 9 software and can be used free of charge.
Nope, no sharing apps.
There is no version of iTunes available for Windows Millennium Edition.
Yes. Windows version of itunes will recognize the soundfiles in your mac iTunes library.
If you are sharing with a non-family account holder then yes it is, but family-sharing is legal.
Preferences -> Itunes sharing
This is not possible. There is no Linux version of iTunes, and the Windows version does not work properly under Wine. There are far better media players for Linux, and other tools for syncing your iPod.
