This might sound big, but if we could do this, imagine the new things we could with MSN? We develop a new Protocol and a patch to convert. This way, we could do LOADS more things with MSN, such as animated DP's, animated CE's, CE's in names, invisable mode, etc. etc.
This might be impossible or too hard, but worth a try? i'd do it, but i have abaslute NO programming knowledge, what so ever
