The Gilder Technology Report is a technology strategy newsletter concerned with emerging technologies that will shape the landscape of the world of broad bandwidth. The Storewidth paradigm is defined by Gilder as the emerging architecture of the Internet, represented by the future convergence of abundant bandwidth and mass data storage into readily accessible information. The monthly Report focuses those companies whose breakthrough technology is pivotal to these new paradigms, and includes brief summations of ascendant technologies and representative companies possessing these technologies.

With the ultimate edge advantage, close proximity to the end user, Mangosoft has accomplished what highly distributed content delivery networks have attempted for years. Mangosoft has effectively transformed the desktop into the smartest, most efficient cache on the network, a cache that knows exactly what to cache, when, and for how long, said Mary Collins, a Gilder technology analyst.

Mangosoft's Mangomind is a breakthrough Internet file sharing service that extends accessibility to files on a user's PC to anyone on the Internet to facilitate business collaboration. Mangomind combines advances in distributed, peer-to-peer technology with Internet storage accessibility that breaks the traditional boundaries of the Local Area Network (LAN). Mangomind allows users to set access permissions for files and folders and employs 128-bit data encryption (128-bit) at the client (user) to ensure that all files are securely transmitted and stored.

"Mangomind extends the clients existing network services by allowing secure storage and sharing of data between members of extended business workgroups," added Collins. "While traditional VPNs require dedicated phone lines and dedicated IT staff to collect user profiles of remote peering partners and to install, configure, and manage VPN hardware, Mangosoft was able to set Gilder Publishing up with our very own VPN and remote Internet storage cache with a single e-mail."

"Mangomind was developed to bring transparent, LAN-like file sharing capabilities to the Internet in a secure and efficient manner. Our technology is a breakthrough in leveraging the power and ubiquity of the Internet, said Scott Davis, Mangosoft's vice president and chief technology officer. "We are very pleased to be recognized by the Gilder Technology Group for our contribution in bringing storewidth file services to the Internet."
