Filter parameters extension

[Ben Smith]

Hi all,

We're finding the filterValue, filterBy, filterOp combinations really  
useful and were wondering where best to suggest some extensions.  
Specifically, could we have some filter operations like notcontains  
and notequals? Would this be something to take to the OpenSocial lists?

Additionally, the filter operations 'contains', 'equals, 'startsWith'  
and 'present' make sense when you're filtering on simple values, but  
are confusing when applied to @friends. Should we be only using  
'contains' when filtering out @friends?

Cheers,
Ben Smith
