Thank you kindly, gmaxwell, for clearing that up for me. I simply thought that it looked weird and needed a trusted opinion.
On that note, this is great news. At first, we had Jimmy saying no. Then the other idea of organizing the editors was shut down with a valid reason. Now we have Wikimedia NYC accepting Bitcoin on its own accord. And how many other chapters are there? And what's the likelihood of having all of them accept Bitcoin as a donation option? And who's in charge of trying to make sure that this comes to pass? And what are we waiting for?
The decisions of the chapters are up to the chapters. They may each have their own personnel issues (e.g. lack of an available trusted party to handle the digital donations), interpretations of local laws, hunger for funding, etc.
The list of chapters is here:

It's worth noting that not all chapters are equal. Some are large and active, some are new, inexperienced, and some are mostly idle. Some are not actively soliciting donations because they don't have the organizational maturity to handle them (and just get grants from Wikimedia to run projects that cost money), etc.
Off the top of my head: Some of the larger and more active chapters are Germany, Netherlands, France, Israel, Australia, Italy, UK, and Argentina.
My gut impression is that Germany won't care much (they are by far the largest chapter, and have a lot of income already) and that UK will blow you off with bitcoin-is-bad+wacko-law-interpretations. Best bet is contacting a chapter near you or ones associated with languages that you speak. Since chapters have a regional (and often language specific) focus, people closer to the chapter are in a better position to interact with and evaluate them.
Wikimedia (washington) DC is a new, smaller chapter that was just recently formed. It has a lot of cultural overlap with the NY chapter so it might be receptive too.
I feel kinda silly for not suggesting trying to get the chapters to take bitcoin before... in general its a pretty good fit: as smaller organizations the chapters can be a little more agile... and if one or another is infected with the bitcoin-is-bad meme there are others to try. The ones who will accept it get the benefit.
And it will build up a base of experience with accepting bitcoin donations within the Wikimedia family.
