We're looking for a PHP class that will allow us to send Instant Messages to the Jabber / Google Talk networks, and preferably others as well, including AOL Instant Messanger, MSN, Yahoo, etc.
The goal is to alert users of our website when updates have been made to their account. We will have the user's IM name and what type of service they are on (aol im, google talk, ...), and would like to send them a message from our username.
We have plans in the future to be able to receive messages, if you can help us with receiving messages too, please say so in a private message, and let us know what your bid on that will be.
Please bid on creating an interface that will work with at least Google Talk, AOL IM, Yahoo, and MSN. If not possible, please let us know what the cost would be per service.
