I am developing a intranet for my work, and will probably use Squirrelmail for a internal web based internal e-mail system. My bosses though have asked if there can be a messenger client option incorporated into the weblail page, so when a user logs into their account, on say the left hand side there is the messenger client, built into the webpage, as they dont want a popup. That way, as we work in a call centre, if someone is on the phone, then a real time message can still be sent to them.
The intranet will be run off Apache, either on a Windows or Linux box as its only for 40-50 people max.
Any ideas??
