Wirelessly sync what exactly?
If you mean media files (via iTunes) then if you have iTunes Match you can sync everything via iTunes. Mail (as long as the account is IMAP-compatible) is synchronized through the mail server. If you mean arbitrary data files, you can use a cloud service like Dropbox - it even has a LANSync feature for when the two computers are on the same network.
What is your use case, exactly?
