I totally agree with this statement.

My job is in sales and I am teaming up with "sales" engineers. The bottom line is that they have the technical knowledge and I just have to manage/prioritise the relation with the Customer.

>> I am doing the meetings instead of them >>> They don't like to be disturbed while producing, or move from their chair >>> hipchat is the best option for me >>> they are dedicated on different tasks/projects

So, when they are working remotely is fine for me as long as us don't loose the intimacy [common language]
