Systems and methods for distributing Electronic Medical Records (EMR) from a private practice to authorized mobile devices are presented. EMR data can be exchanged from a private practice with a remote mobile device via an intermediary mobile access service. The service can include one or more servers that tunnel EMR data between the mobile devices and the practice, where a relay server located at the service communicates via an a priori instantiated persistent session with a relay client installed at the practice. The persistent session can be maintained by the relay client thus reducing the burden on the practice to configure or change local network infrastructure.
