Peer-to-peer under the spotlight |  Networking

At the Demo 2001 show this week in Phoenix, at least three companies will launch
peer-to-peer platforms upon which corporate developers can create applications.

United Devices Inc., based in Austin, Texas, already has its first corporate
customer for its MetaProcessor Platform that aggregates idle computer resources
on distributed client systems. The product will officially ship in March.

Exodus Communications Inc., the collocation and hosting giant, is piloting
the use of the MetaProcessor platform to do Web site load and stress testing
with actual PCs, rather than simulating Web usage.

United Devices' technology uses a server as a "command center" to
manage processor activity across a distributed application.

Users willing to participate download a client software component that allows
the server to poll the PC for configuration information and the availability
of unused processor cycles. The server matches PC capability against jobs it
needs to run, distributing processing tasks to appropriate systems.

"There is no obvious degradation in the performance of a PC when idle
processor cycles are used in the background, " said Jikku Venkat, vice
president of engineering at United Devices.

United's platform is also being used in cancer research and for protein sequencing

Ecertain is taking a different approach to peer-to-peer. The company already
offers a server-based product called Digital Certainty, which verifies and creates
an audit trail of all incoming and outgoing files. This includes the time and
date of transmission, time and date of receipt, and any other information to
prove with legal certainty that a transaction took place.

The company is now set to launch a peer-to-peer version of the product for
the medical records market. In the medical market, transmissions of large files,
such as MRIs (magnetic resonance images) and X-rays, can be costly in a client/server

"In medical, there is a high level of transactions and an unknown file
size. It is important to keep transaction costs low so we created a peer-to-peer
solution," said Neil Iscoe, CEO and founder of Ecertain, in Austin, Texas.

Because the peer-to-peer solution is not dependent on a central server system
for file transfer between PCs, it reduces the cost of transmission as well as
the time while still being able to verify that a record was sent or received.
Verification is critical for compliance with new U.S. government regulations
on electronic transfer of medical records.

2Bridge, based in San Francisco, will unveil a product called 2Bridge Personal
Server that its founder, Mansoor Zakaria, calls "file sharing on steroids."
