Good question! I don't have (yet or ever?) my own N900, but of all the 'apps' that I have written, it is the one that is 'pure python', so my guess is that it would have the best chance of working out-of-the-box. For now, I depend on others (such as yourself) to 'test' and report back to me and others what success or problems are experienced.

However, if it does *not* work, it will be tricky to 'fix' it
