Thanks for the ideas!

Previously I have used iPhone and iPod (and occasionally iTunes) to play the files in question. Alas N900 is no iPhone , so I think i'll try splitting the files. Maybe I'll manage to script a solution to do that somewhat automatically, and feed those files to my N900 either via a private rss/podcast feed or something similar. I'll also give Panucci a try, before doing that. I'm using gPodder as my podcast downloader, and it uses Maemo's Media Player as media player. Maybe that can be changed to Panucci if it works out to be better.

Still, I hope someday these kind of files will play, as I suppose that there are at least few persons who like their audiobooks, without too much extra hassle.
