Abstract

Applications, systems and methods for efficiently accessing and controlling data of devices among multiple computers over a network. Peer-to-peer exchanges of data between private computers is made possible while providing seamless, firewall-compliant connectivity. Such functionality is available even among private users over a public network, and even when multiple firewalls must be passed through. A firewall compliant connection may be established between a local computer and at least one remote computer; at least one file on a storage device associated with one of the computers is selected, and securely sent to at least one other computer over the secure connections. Computers may be connected over a wide area network with or without a connection server, with or without a VPN.
