I was taken aback by "Simply post your request in this thread...". I guess that means you simply couldn't implement a request and collateral mechanism inside the client itself instead of hosting it on a potentially moderated centralized thread which really sound silly.
i guess it's all about better exposure and minimizing the risk of misuse of the service by recording requests publicly. i agree, as bantam appreciates in value there should be in wallet mechanism to automate the process. it could work.
