Abstract: A network address translation (NAT) gateway intercepts packets and determines whether they contain multicast domain name server (mDNS) query or response messages. Upon receiving an mDNS message, the NAT gateway performs address translation to assign a new source address and stores the original source address in a translation table. The NAT gateway then forwards the message to all adjacent networks in order to expand the reach of the packet. If the mDNS messages establish a new client-server connection, the NAT gateway brokers the connection by either acting as a proxy or continuing to perform network address translation.

Abstract: An integrated personal information management system is described. In one embodiment, for example, an integrated personal information management system is described that comprises: a receptacle holding at least one paper page that is capable of receiving pen strokes from a digital pen; a digital pen for recording pen strokes when a user writes on a particular paper page; a page identifier for identifying the particular paper page on which the user is writing; and a handheld personal information device in communication with the digital pen and page identifier for processing the recorded pen strokes associated with the particular paper page and displaying the processing results on a display screen.
