Lotus Notes like application

["Jieyao" <jieyao@altmedia.com.sg>]

Hi,

We were discussing Linux vs Win one day and we got stuck when someone 
mentioned that there isn't any Linux application that does what Lotus Notes 
does. Indeed, off hand we knew of nothing that does work flow stuff or what is 
commonly termed 'groupware'.

Is this true? I feel that there might be some application that does a bit here and 
there of what Notes does, but not one as integated as Notes.
Perhaps there is a project some where taking care of this?

Thanks.
