[Livius Agrippa]

Hi,

I have a new homework from my boss :).
I should integrate a groupware application in Typo3.
And I have to find a solution for this problem. For the moment I have 
very few information about this subject.

If somebody has some experince with such a stuff, please tell me some 
directions or advices.

Thank you for any advice (it would be very appreciated).
