In the interest of full disclosure, it needs to be said that "shelly Watson" is apparently affiliated in some way to Comm100, according to her email address.
@shelly: You should mention that in your posts, lest people get the idea that you provide impartial advice.
Having said that, I've once built a prototype integration with the Comm100 stuff for a web site I was working on, and found it easy to get started with. In the end we didn't pursue live customer chat, though, so I can't speak to its operational characteristics.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
