Synchronizing, both the results of the DKP spent but of the current DKP from guild websites.
Not sure how hard it would be to Add a time stamp to the GetGRSS but have another feature in game if you have 2 different raid leaders and one hasn't done updated there current DKP table that the add on offers them to sync with someone in guild that may have updated later than him.
Just thinking out loud, thought I'd throw in 2 cents to the suggestion box
