// Grid
//
// We no longer need a shared secret between grid
// servers. Anything a server requests from another
// server is either done on behalf of a user, in which
// case there is a token, or on behalf of a region,
// which has a session. So, no more keys.
// If sniffing on the local lan is an issue, admins
// need to take approriate action (IPSec is recommended)
// to secure inter-server traffic.
//////////////////////////////////////////////////////
// NOTE
//
// Session IDs are not handled here. After obtaining
// a token, the session ID regions use can be
// obtained from the presence service.
