PageRank, Alexarank integration

Hi,

I would like to ask you if there is possibility to show ranks in the certain site/post/link in the directory plugin.

Just few ideas about this topic:
- It could be good if there is ranks and could be setup listing order from highest to lowest ranks
- own rank system - something like aritmetic average of existing ranking system. This could help to do the listing order
- API for connecting another ranks systems
- widget with hiest ranks following the subcategory
