Hi,
Perhaps you remember that I started working on porting the zimlib to Symbian and to implement a viewer using Qt some time ago.
The viewer is now called "WikiOnBoard". Source code and symbian install packages can be downloaded from http://wiki.github.com/cip/WikiOnBoard/
Instructions how to install and use it can be found there as well.
If you like, or don´t like this app, if it works fine or it you encounter problems, if you have any suggestions for new features or other feedback, I´d happy if you let me know. (Either on this mailing list or on the wikionboard web page.)
While currently only Symbian binaries are available it is pretty easy to port it other platforms which support Qt. So if you own an interesting device (in particular the N900 would make sense) and are willing to test, please let me know and I will try to build binaries for this devices.
I´d be happy to support you if you want to show the app at Linuxtag. A N900 (as Linux based) would be perfect if such a device is available and I can finish porting in time, but perhaps Symbian may be feasible as well. (Finally it is open source, although current hand sets use a pre-open source version). Please let me know if you are interested in some of these options.
Best regards, Christian
