I believe the private key of the applications on Android Market must have a validity period ending after 22 October 2033.

Requirements enforced by the Android Market server:

How about the AppHQ ?
Is there any requirement or recommendation for validity period of certificate to sign apps on AppHQ ?
Does the AppHQ requirement comply with the Android Market requirement ?
