Have not tried what you want.
But is this program any good or useful
Here is a link to others like it on CNET and doing a search could locate more
Does anyone know of any software for Windows that is out there to download in a freeware or open-source form that provides encryption for AIM, Yahoo Messenger, ICQ, and MSN messenger at the same time? The best I can find is a few programs that require a purchase costing $20.00 or more to use, and one that works, but only on one messenger service at at time. Any suggestions or help on this?
