Anycast and windows servers

[Sean Donelan <sean () donelan com>]

How well does Anycast work with Windows 2000 or XP servers?  Is the
Microsoft OSPF implementation good enough to use or do people port another
routing implementation?

Yeah, I know about Unix/Linux.  All the large scale anycast deployments
I know about are on unix, but I was wondering if anyone has tried it
using windows.
