It might be wise to consider requiring people to not require a purpose for donations to SPI but allow general use.
If we allow a specifications of purpose: Who is going to track that and make sure it is really used like that? We need then to have a database of machines etc etc which is quite a headache. Given our limited administrative capabilities I dont think its wise to allow people to restrict use for a certain purpose. Maybe restrict use for a project but then the project should track the stuff.
