No such 3rd Party DLL exists. Also, multi-threading might have to be used for Video. So It's better that the client does it itself.
Also, When chatting with someone, do you really want to tell them to download a DLL and install a script just to share video with you? They probably wouldn't do it. It's better to have this kind of feature in-built. Then a simple CTCP VERSION will tell you if that person can share Video with you.
Otherwise, you might aswell just tell them to open netmeeting, as they probably have it installed already (/run conf).
Anyway, this feature was suggested as an addition to the mIRC client. There are other way to do it, ofcourse. You can simply use the 'callto:' URL syntax in a nicklist popup, and have Netmeeting fire up. However, anybody who has used Netmeeting for a reasonable amount of time will know how buggy and Second rate it is, compared to other MS products. It's the best program of it's kind, and yet Crap at the same time.
