If you read the history thread I linked to, you will see that a past fundraising attempt reached $10000. Back then it was run by BeUnited.org, which was the entity coordinating efforts toward evolution of the BeAPI between Haiku, Zeta, Cosmoe and BlueEyedOS. However, when they approached GoBe, the result was that cleaning up the source code and releasing it into the open source world would cost something around $200000. This was way out of reach back then, and still is today.
I don’t understand why people insist that Haiku, Inc should be in charge of everything. Haiku, inc is a support association for developping the Haiku operating system. It is not their goal to act as a funding platform for such things or buy deprecated sourcecode from defunct companies. And, they already barely have time to handle their current activities, anyway.
If someone is really serious about getting GoBe open sourced, the first step is locating whoever owns the sourcecode these days, and ask them for their current estimate of the cost for open sourcing it or acquiring the codebase from them (no NDA, just buy the whole damn thing and full rights for it). Then, run a Kickstarter or so to fund your effort. Once you have done that, you can donate the source to Haiku, inc if you really want them to own the code.
Alternatively, I’d be fine with GoBe being a commercial app for Haiku and I’d buy a copy, if it allows working with modern fileformats (docx and the like or odt). So, is someone willing to run a company to maintain and distribute it?
