Early equipment tended to operate at nuch lower rates than the advertised 400Mbit/sec. It is unclear what sort of data rates are actually attained using Firewire.
Firewire does not currently (1997) support fibre optic connections. A study group is looking at adding the capability as well as higher transmission speeds.
As of 1998, it is reported that Apple is demanding high licensing fees for use of the "firewire" name. It has been projected that many products may be sold as "IEEE-1394" without the "firewire" moniker. Sony uses a subset without power wiring in the cable called i-Link for their Digital Video equipment.
