Thank you, maxinflixion.

Maemo-Wordpy certainly does show promise. I hope it is still in active development, as I can see some room for improvement. For one thing it doesn't auto-remember the entry you typed. Unless I missed that. Coming from a true offline blogging client, which generates the html output ... that does seem strange. Though I guess you can type your entry, save it. Type another. Save it. Etc. Then publish them, re-open to edit etc. And you can always access it online.

Anyhow, I will explore it more. I already posted my first entry from the N800 to a little test blog on wordpress and reported my first bug

I will gladly hear from others about other solutions as well.
