Am in search for similar program that could be uses on the underlying Sametime protocol which is developed by IBM but in vain. I’ve heard my colleague who recommended QuipIM but requires a price tag of USD 4.99. My worries is on the compatibility since there is another application “IBM Sametime” which is made available on Apple App store that is free but doesn’t work. But if you’re using Android, it might seems to be good news to you or anyone who needs it as they are providing free installation now (as of time writing this). Go head over and download, let us know if it works.
Probably it’s time to consider a phone with android platform.
