Save $$$ on licensing?

SQL Server Developer edition does NOT have any limitations on connections,
users, or number of processors or CALS, correct? As long the database is not
used in a production environment.
Our mgmt has recently is ordering only ordering 1 Developer Edition license
for each new SQL database server we are installing. We have 15 servers on
order and each is a dual processor. This represents a huge cost savings of
not having to purchase per processor licenses as we had done in the past to
accomodate our users acceptance testing -- from thousands of dollars for each
processor to less than $49 for each server.
Would that really save you thousands even though you still buy the full
licences once you go live? I guess if you have a continuing UAT requirement
you will save something in the longer term. A worthy reminder about Dev
Edition anyway :-)
