1. A method for comprehensive processing of open system interconnection (OSI) layers for network/routing isolation and formation of a scalable community of interest providing a hardware and software combined solution that includes open system interconnection 3.5 processing comprising: providing a hardware and software combined solution; providing comprehensive open system interconnection layer 3.5 processing; implementing the comprehensive open system interconnection layer 3.5 processing into the hardware and software combined solution for comprehensive processing of OSI layers for network/routing isolation and formation of a scalable community of interest; wherein the comprehensive open system interconnection layer 3.5 is in between network layer, layer 3, and transport layer, layer 4; forming a first scalable community of interest based on at least a first security policy, wherein the first scalable community of interest admits at least a first set of mobile clients and wherein the first security policy includes a set of contextual flags, including at least an alert level flag and a system status flag; accepting determinable portions of information data at the first set of mobile clients in response to a status condition of the system status flag; receiving, from a first one of the mobile clients, a request to set the alert level flag to an elevated alert level; and upon verification that the first mobile client is authorized to write to the alert level flag, setting the alert level flag to an elevated alert level and admitting at least a second set of mobile clients to the first scalable community of interest.
