No many, but there are definitely indy's around that will do coding, just not a lot of them, there is a guy in Poland that can do it remotely, but he is hard to get as he is pretty busy, and a shop on the west coast that can do it and does trips to NYC once in a while to do coding sessions.

There are also a bunch of guys on the 5series.net forum that have figured out how to do it themselves with a $100 ebay cable and a lot of patience.

Here is the thread about it over on E90post - ordered a cable myself just to see if I can at least read the car and figure a few things out for fun (or massively screw it up in the process - we will see!)
