`ABSTRACT
`(57)
`A client device comprises: (a) a memory, (b) an application
`program, and (c) a signal processing con?guration. The
`memory is con?gured and arranged to facilitate a connection
`of the client device With a target device over a secure com
`munication link created based on (i) an address request gen
`erated by the client device, and (ii) a determination as a result
`of the address request that the target device is a device With
`Which a secure communication link can be established When
`the requested address is identi?ed in an address lookup. The
`application program is con?gured and arranged so as to alloW
`participation in audio/video communications With the target
`device over the secure communication link once the secure
`communication link is established. The signal processing
`con?guration is arranged to execute the application program.
