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.
