Unlimited user site licenses are exactly the sort of agreements that provide greater benefit to the university. This is the most equitable way to share the expenditure. There's no room for this cost increase in my 2000-01 budget. If this puts too much of strain on a school's or department's budget, the cost may be spread over 2 fiscal years . A perpetual software license confers to the licensee the right to use in perpetuity the version of an application that was current at the time of signing a licensing agreement.
Maintenance means different things to different software vendors.
In the case of SPSS, it means the right to all service releases and version upgrades to SPSS within the calendar year for which a maintenance fee has been paid . All SPSS licenses would be frozen at the version that was current in the year for which the last maintenance fee was paid. Unless the user base drops off precipitously, there is no reason to stop funding the annual maintenance fee. This is not expected to happen in the foreseeable future. Full-time employees of the university are licensed to use SPSS for Windows on their home computers.
