We could slowly develop this thread; if it is OK by Werk, and perhaps someone could look at suitable code changes to allow these sensors to be used, to allow us to use these often very high quality sensors occasionally found on ebay from old research projects.

To me it's OK. If at any time something come out, that I find useful to the project, I have no problem in thinking about adding it.
Of course, it must not break compatibility with existing hardware, and don't imply adding much code (The Nano memory is already used almost to the limit).
