I am aware that there are some differences. However, given the ease with
which Adelaide modifies the buses for O-Bahn usage, I doubt there's a huge
challenge. I do know that, from time to time, problems have cropped up. For
example, at one time, some types of bus experienced excessive tyre wear.
But nothing to affect operations as far as the public was concerned.

Now, perhaps there is a reason why double articulated buses wouldn't work
on the O-Bahn. On the other hand, they are supposed to be designed to track
exactly over their guides. Point being though surely if anything, it's a
reason to call it a trial? Try it, if it doesn't work, no loss of face. If
it works, then everyone concerned is covered in glory.

Maybe, like the Julien Patent battery tram, they are going to try and hawk
it round the country and try it everywhere.
