I'm taking on a new project for an engineering company based in NY. They just opened an office in Chicago and would like the 2 offices to be seamless. They are going to use VoIP and a VPN (T-1 speed) to connect the 2 offices. My question is what is the best way to handle the AutoCAD drawings? People from either office could be working on any file at different times of the day. Anyone else had to deal with this?
