Is there a way to accomplish what you want using existing standards and existing webs in a different context? Inventing a novel standard for an existing network is quixotic. But some of the greatest success stories in current times are about firms that master one network and then use its embedded standards to exploit an established network in need of improvement. This process is called "interfection." The present revolution in telephony is all about zealous internet firms that are interfecting the old Bell-head world of moving voices with newly established protocols for moving data on the internet (known as internet protocols, or IP). The huge increasing returns that spin off the internet give them a great advantage. Indeed, one telephony standard after another is falling before the relentless march of IP. Likewise, aggressive companies are leveraging the established desktop standard of Windows NT--with all its plentitude effects--to interfect new domains such as telephone switching gear. Even the huge cable TV networks have something to offer. The emerging standards for video transmission, such as MPEG, are trying to migrate onto the internet. In choosing which standard to back, consider dominant standards outside your current network that could interfect your own turf.
