IEEE488 (also known as HPIB) transfers to PC's can be as fast or faster than
LAN connections, depending on LAN traffic (my experience with the HPIB
connection is using the WHPPC package from Verity). However, there are the
following tradeoff's:
1. HPIB connections are subject to a maximum distance limitation of around 8
meters. LAN's can transmit a few hundred meters or more, depending on the
infrastructure (wiring type, hubs, repeaters, routers, etc.).
2. HPIB connections are essentially a one-to-one transfer. At our site, we
use one-to-many (instrument to other instrument/analysis PC/file server)
transfers that can only be served conveniently through a LAN.

Just some things to keep in mind.
