Clientless Bot for Diablo II and Battle net

This is going to be fairly hard to explain so I will give as much detail as I possibly can. I need someone who is familiar with [login to view URL] from Blizzard and, if possible, the game Diablo II: Lord of Destruction. I currently have a bot that is capable of going into a random game and typing something on the screen. The bot currently uses AutoIt. Here is the link to the website where the bot can be found: [login to view URL] What I need is a bot like this but one that is clientless, meaning it doesn't need the game to run. I would be able to go into a Diablo II game on [login to view URL] and type a message of whatever I wanted it too. It must also be able to use proxies to connect to [login to view URL] as well. And if it is not possible to make it clientless, have it be so that it can run multiple time per computer/ip address. That is what the proxies are for. If someone can do this please let me know and also feel free to ask me any questions. I understand this will probably be a hard task to accomplish but it is very important. And make sure you download the file to understand what is going on. It is easier to explain that way. Or, if someone here actually played the game, that would also make it easier as well. Thank you all and good luck.
