ok, so i'm happy with iphoneigtd, but i only have a trial .mac account, and i wont be getting a full one. Also, you have to have an internet connection at the time.

Is it possible that a native app could be ported, using a similar interface to the web one, but that could be populated by a file (e.g. backup to csv in iGTD) that was uploaded via ssh to a file such as /var/mobile/media/iGTD/ or something like that?
Also, could there be a display for comments, like if the web interface was kept, could the tasks be links to another page with their comments and other things?
