ReportBuilder Server Edition currently includes a single developer license for ReportBuilder Enterprise and a single developer license to ReportBuilder Server. Also included is a Server Deployment license for a single CPU. This enables you to install a report server solution to a single CPU machine. Additional Server Deployment licenses are US $249.00 per CPU. Thus to deploy a server solution to a dual processor machine requires two deployment licenses. A report server can support as many clients as the hardware will allow. In summary, the licensing is per server CPU, not per client seat.
ReportBuilder Server, US $1,199
Server Deployment License, US $249
