Maybe this is what the Haiku community needs to get exciting again and attract new developers and users.
There has been a few posts about crowd funding:
The one by mmadia (https://www.haiku-os.org/blog/mmadia/2013-05-25_research_crowdfunding) provides insight into the back fees also involved with such a campaign.
The one by lxstoian (https://www.haiku-os.org/community/forum/kickstarter_haiku_campaign) and the community comments centered on producing a HaikuBox.
There are fees from the crowd funding platform and payment processing entities to be aware of. Aiming at 10,000 Euros for the project it-self means raising ~13,500 Euros. Also, since it appears that the whole code base, including the intellectual property, would be considered, Haiku Inc. would like have to seek legal advices for which there are usually fees to be paid. It may be possible to find a lawyer with knowledge in this area and is enthusiastic enough about Haiku to do this "pro bono".
In the end, to get the necessary 10,000 Euros for the project, the crowd funding campaign would likely have to aim at 15,000 Euros.
Bringing Refractions under the Haiku Inc. umbrella could be a start of a providing a suite of excellent applications as part of the R1 distribution.
Another thing, this could be an excellent well-defined way to practice crowd funding to tackle something much bigger/challenging - like getting Productive, bringing Wine to Haiku, or even designing a HaikuBox.
As an end-user, I have a preference for applications which have been developed originally for BeOS, or eventually for Haiku, than a port from Linux attempting to mimic a major commercial application.
