Nicolai, and others, I'd like to take the opportunity to thank all of those stepping up to the call for contributions. Every little bit helps.
For those who ask, the OpenBSD Foundation is the best path for contributions. I hope some larger contributors will step up, to take a more long term view (like Google does). Rather than the "little people" funding our efforts. Many of the things we do in OpenBSD are often incorporated into products made by multi-million dollar companies. This is not a BSD vs GPL issue, it is about a plain lack of goodwill, something you cannot mandate via a license. A lack of goodwill is effectively badwill. There is a good list in the last paragraph of the OpenSSH web site. Maybe the community's activism can make inroads there which we have not been able to.
