Creating a Remote DR Site for Clustered Master Secret Server

Gents,

I am light BT user but am trying to get this question answred.

PROD site has WCS with Clustered A/A SQL servers, Clustered BizTalk Servers.  We have the ENT SSO clustered in the PROD site.  We are setting up a DR site connected via PPP T1.  Single Windows Domain.

What do we do about clustering the EntSSO at the DR site since from what I understand ther can only be One Master Secret Server at any time?

Let me know if this is insufficient information  and I can provide more details.

Thanks in advance for caring to look at this.

Colin.
