Anyone know a fast Runescape name checking method?

I came up with a neat little idea that will be very quick to code, and hopefully benefit most of the Runescape community. It came to me after running Blupig's programs, although he uses a method that I can't use on a web-based script.

I've tried both the adv. log and hiscore methods, anyone know of any other?

Code:

removed for anti leech for now

This is what I've done for hiscore method, but it's ridiculously slow. I did something similar for adv. log method, but about the same speed.
