Two users on the LAN running empathy can see each other under 'People Nearby' (telepathy-salut implementing link-local XMPP protocol). Is there a chat program in Windows that can see ubuntu users on a LAN running empathy only? I would really not like to set up a Jabber LAN server.

I did install the latest stable version of Pidgin on Windows. Use the Bonjour protocol. When you try to connect you'll be prompted with help and a suggestion to visit a wiki help page of Pidgin related to Bonjour. If you don't find it, then visit this link.
I've made a local wireless network between an Ubuntu 12.10 system and a Windows 7 system. The Windows 7 system I installed Bonjour on so that the link-local XMPP thing would work.
I sent a message from Ubuntu to the Windows 7 computer. The Windows 7 computer was 32-bit so I didn't need to do the extra steps necessary if my Windows was 64-bit. A reply was sent from Windows 7 to Ubuntu and it went through just fine.
