The users notebook shall sync to two servers with different
data. I.e. user works on data of firm A, then syncs to As
server. Afterwards user works on data of firm B which is
also synced but this time to firm Bs server. The local data
of A and B is kept in different folders on the notebook.

From what I remember from the client-installation, you have
to give the client a fixed local path. Do I remember this
correct? Is there any workaround for this?
