As the title states, i suggest replacing rune head with a custom built, in-house hosted alternative.
I came to horses with the idea a few months ago and asked her to bring it up without my name attached and didn't receive positive or negative feedback so...whatever.
I'll write it, it's nothing more complicated than pulling stats from the lite hiscores every time someone refreshes it, populating a database and displaying it. Assuming no crazy server incompatibilities it shouldn't take more than a month or two accounting for prior commitments. Plus if it goes down well i can read up on jquery to furnish it with some nice graphs and other graphical things like progress charts. Aside from that i'd write most if not all of it in Php, html, sql and css because thats what i know.
I've already written the extraction code but i stopped a while ago because i can fully see this getting shot down in flames.
