Hey blackdog,
I dont know how you would exactly do that, but since I do not own these smilies and they are not copyrighted, and considering that this is a public forum, any one is subject to 'steal' them by saving the individual gif files.
Once you have the file saved, then you could attach them with your emails, or embed them with a rich html email, but I dont know anything about messenger services since I do not use them-
Cya
