[Samba] domain master list - cross subnet?

I'll rephrase the question:

Does anyone, using samba 3 as a PDC master browser on a subnet, see 
other subnet's on the WAN?

For instance, if your subnet is dude.udump.edu, can your samba master 
browse list see the windows domain chick.udump.edu (assuming it exists)?

If I just know it's possible, then I know I'm doing something wrong.
