Standard disclaimer, IANAG (I Am Not A Googler):

As I understand it, user preferences are an iGoogleism, and,  
generally speaking, will not be supported in most OpenSocial  
containers.  I've heard  reports that they work in Orkut, but, unless  
we here otherwise from the powers that be, you shouldn't depend on them.

Of course, at the moment, data storage support in most containers is  
pretty, well, uh, FAIL.  Plaxo *MAY* have a working data storage  
implementation, but it would be great if someone could verify this.
