Shibboleth Developers

Has anyone installed shibboleth IDP on windows server 2003 x64.

We are contemplating purchasing a Fujitsu Xeon dual core processor, which is 
64 bit. We were then planning to put windows 2003 x64 on the server, but are 
a little concerned that the shibboleth IDP software will not work.

I would appreciate it if anyone could give me an update on how they 
progressed if they used the above solution or on lack of progression if this 
was the case.

Many Thanks

Martina
