Hi
Win XP, Vista, and all variants of Win 7 are capable to connect via
peer-to-peer Ethernet network.
To analyze the differences in capacity and usage would take a chapter in a
book, and thus it is not suitable for a Newsgroups short answer.
If you have a specific question. I.e., you need something specific to be
done and you want to make sure that it works, then ask the question.

Can anyone tell me the peer-to-peer networking capabilities of Windows XP,
including the essential differences to Windows 7 Professional and Windows
7
Home Edition?
