Daisy Chaining Ethernet??
Norman Foster
cards and adapters that can be daisy chained without a hub for up to eight
machines. Anyone heard any more details on this idea???
Thanx for any info.

Sorry for the long post, but this should answer most of your questions:
Farallon's EtherWave cards, transceivers and adapters for Macintosh and PC
computers incorporate technology that provides the industry's easiest
solution for creating and/or expanding Ethernet networks.
Farallon has applied for patents for two EtherWave innovations:
--the daisy-chainable design of EtherWave technology that enables users to
run 10BASE-T Ethernet over unshielded twisted-pair wiring without requiring
a hub.
--the auto-crossover feature that greatly simplifies installation and
network moves and changes by automatically selecting the appropriate
configuration for any 10BASE-T connection.
Additionally, Farallon is incorporating 3Com's third generation Parallel
Tasking technology into its EtherWave ISA Card. By combining 3Com
technology with EtherWave, Farallon is able to provide PC users with the
best price/performance Ethernet connection option on the market.
Two 10BASE-T RJ-45 ports on each product allow for daisy-chain
configuration. Two devices can be connected to a single network hub port,
eliminating the need to pull additional wire to an office or cubicle.
The products work with peer-to-peer software such as Farallon's Timbuktu
cross-platform network application software, as well as Novell NetWare
Lite, Microsoft Windows for Workgroups and Artisoft LANtastic.
EtherWave products can be combined with other hub-based solutions to build
larger Ethernet networks. For example, a single Farallon Ether10-T Starletª
hub can support a workgroup of up to 56 nodes. Multiple Starlet hubs can be
connected together to build larger networks. And, network managers can use
EtherWave adapters, cards and transceivers in combination with any 10BASE-T
hub to build managed networks. EtherWave adheres to all IEEE 802.3 10BASE-T
requirements for a cable segment and is fully 10BASE-T compatible in a
simple daisy chain or when connected to an existing network Ñ without
hardware or software modifications.
EtherWave technology simplifies connection logistics and minimizes
disruption and lost productivity. Unlike Thinnet, EtherWave products are
self-terminating, isolating cable breaks and shielding the rest of a
network as additional nodes are being added.
Two EtherWave innovations are particularly helpful during network additions
or moves. First, because the technology combines standard 10BASE-T hub and
transceiver technologies into a single application specific integrated
circuit (ASIC), EtherWave devices behave like non-reclocking repeaters. As
a result, a user can add nodes to 10BASE-T networks without impacting hop
count limitations. Second, network changes are greatly simplified because
an auto-crossover feature enables a user to attach to any existing 10BASE-T
hub port or jack.
EtherWave Macintosh Adapters, EtherWave Printer Adapters and EtherWave
Newton Adapters offer customers a fast and easy means of attaching
non-Ethernet devices to Ethernet networks. The EtherWave Macintosh Adapter
for PowerBooks and Macintosh computers without expansion slots features a
high-speed serial port driver, enabling performance equal to or better than
small computer systems interface (SCSI) products without requiring
cumbersome SCSI cables and installation. The EtherWave Newton Adapter
provides the first way for MessagePad users to connect directly to
Ethernet, enabling them to access networked resources and information.
