I don't think that the reputation of Google among the larger library community should have much of an impact on the hosting decision. Google does a lot of great things, and a lot of not so great things. I think that the things it does around hosting open source projects should be the major contributing factor in the decision. I also agree that the decision on hosting shouldn't be taken lightly and perhaps shouldn't be undertaken with the intention of making that decision in a single day. The much more pressing matter (in my opinion) is that the code is currently not available for download by end-users (I myself am looking to download it). While the decision for long-term hosting is being made, at least, a copy of the most recent stable release should be made available immediately and linked to via koha.org. The only thing that having no end product to download is doing is losing the project end users.
