Configurable ratings plugin

I’ve seen quite a few plugins that seem to do the job reasonably well, and I don’t know if this is a specific issue with me or if there are more people after a plugin that has more options with regards to ratings.

Basically the following is the sort of thing I am looking of in a ratings plugin:

* Ability to place rating anywhere on a post (under the heading or next to it for example)

* ability to change the format of the ratings – for example, the choice between %, x/10, x/10 etc

* ability to change the image of the rating based upon category – for example, for music I would want to use headphones, for film I would like to use a reel, for games a space invaders alien thingy. User makes a post in the game category, ticks the game box, adds the rating out of x and it’s automatically displayed as the appropriate category image.

*ability to have a total score which is then aggregated by readers – so a user visits, sees something has an author rating of 5 udders out of 10, and decides they want to give it 6 udders out of 10 – the author rating would then (in brackets) have an average reader rating of 6 out of 10 udders perhaps displayed with the number 6 and then the image of the udder).

That’s all I’m after. I dont’ mean to be flippant when I say “all I’m after”, I appreciate the complexities and the lack of understanding I have on how a plugin is made, but what if someone was able to take an existing plugin and then work from that?

I have looked at structured blogging, and it’s lack of multipages is a turn off – other than that I think it is a very fine plugin. Except they way it handles the category slug which should perhaps take the title from the title of the item rather than the title of the post – but perhaps this is forced by WP?

I’m not a coder or programmer so I wouldn’t know what to do or how to do it, I’m hoping some kind soul can come up with sometehing that matches this description.

Thanks for reading:)
