Simply put, echoWare enables any peer-to-peer or client-server
application to utilize a "packet relay server" approach in order to
achieve end-to-end connectivity without adjusting any intervening
firewalls or NAT'ing routers. Many remote access applications
have a "packet relay server" capability to them (e.g, GoToMyPC,
GoToAssist, and others), but echoWare is the first software
package we know of that allows any Internet application to quickly
and easily incorporate this capability.
