Nah, doesn't realy solve anything, might helpt for you a bit, but not for everyone. Let's all together find out how the client sends and receives the data and let's create our own client, lol :P. If the mudclient would just be ripped again this would be better possible, but with a lot of work with packetsniffers it would be kinda doable, rofl, dunno how happy jagex would be with this though since it could be exploited in order to create bots, but you could also create your own runescape looks lol. And design it with any programming language you would like :P.
