http://www.w3.org/2009/03/widgets-pag/cfpa

The W3C hereby issues a call for prior art on US patent 5,764,992 [1] 
that may apply to the Widgets updates specification[2]. Pursuant to 
its rights under W3C's Patent Policy, Apple Inc. has excluded all 
claims of the aforementioned patent from the W3C Royalty-Free License 
commitment. The PAG seeks information about software update systems 
available before June 1995 that offer a viable solution that may apply 
to the use of updates in Widgets. People who wish to provide feedback 
should refer to the call[3] for more information or write back to 
public-widgets-pag@w3.org

Please distribute this call for prior art as widely as possible.
