Depends on who's using it. From the LabVIEW Release Notes:
LabVIEW supports both single-seat and multi-seat licenses. Single-seat
licensing is the use of LabVIEW on up to three computers but by only one
user. Multi-seat, or volume, licensing is the use of LabVIEW on several
computers or by several users. Each seat using LabVIEW must have a valid
license from a license server. Refer to the National Instruments Web site at
ni.com/license for more information.
