I like Aeolus or the other Aeris one the best. But let's not make this any more difficult than it must be for those working on this, or those who will work on it in future. If the name has been already used in a way that could, even if it's unlikely, to cause problem in future it's not worth it. My gut reaction to Hildon was the same as many who opposed it in this thread. But practicalities should trump wrestling over the name of the foundation. I don't think the foundation name will have much visibility compared to what the community will call itself and what domain it will converge itself under. As far as I've understood that can be a different topic.
Actually, you have been very vocal against the name proposed by the people who worked on the initial document.
I found it personally irritating that you named this thread "We need a name for the NFP entity that we're changing to: add your suggestions!" as if it were a search for something new (when in fact you only wanted to replace the proposal already made). Your first post in this thread doesn't make things clear, either. Even though I know that when you wrote it, the proposal for a "Hildon Foundation" was in place, there's nothing in that post to make it clear. To me, it still read: "Hey, we're moving to a new legal entity, do you have any ideas for a name?" instead of "The new entity will probably named Hildon Foundation, but I, jalyst, am against that. Any other suggestions?"
