I just read this morning (from yesterday's NY Times) that Continental's Presidents Club members can now access all PC clubrooms without having a same-day ticket. All you have to do is show your Presidents Club card and photo ID to security and they will then screen you like any other passenger and let you through. Other airlines are expected to follow suit. This was cleared through the Transportation Security Administration.
Great news. Now I can go meet/walk my partner at/to the gate, or hang out in the club, access the shops, spot, etc.
