So what about 1000$ < 10 employees 2500$ < 25 employees 5000$ < 100 employees 10000$ < 1000 employees 20000$ > 1000 employees If the current sponsors agree to this (I think it's very important that they agree) the income would go up significantly because GNOME has quite some sponsors with more than a 1000 employees (HP, Google, Intel, Motorola, Nokia, Novell, Redhat). Furthermore on the low end we also introduce more options.
It does make sense to have a sliding scale that allows smaller organizations to more easily participate in the community by donating and getting recognition. However, as you say, how the fees are handled for larger organizations would need to be negotiated with those organizations which currently donate. Brian
