That is great news! it will be great to be able to run the program on both desktop and N900 and still sync them (however that may be done: rsync, Unison, copy, etc).

May I add another suggestion?

Make it possible to do 3-way comparisons among pySafe databases. This feature should be triggered by the CLI. The 3 files to be compared are: base-file, file1-changed-from-base and file2-changed from base. This feature alone would revolutionize password programs. Here is the typical use case:

• The user adds some entries to her N900 pySafe db;
• The user makes some changes to her Desktop version of PySafe, forgetting to first copy the db from the N900;
• Some days later, the user uses Unison to synchronize many files between N900 and Desktop (example: music, pictures, videos, documents and the pySafe db).
• Unison notices that the pySafe db was edited on both places and so one version cannot overwrite the other without the user losing data.
• Because pySafe supports 3-way merge at the command line invocation, Unison calls "pySafe old-base-common.db desktop-db N900-db". Note: old-base-common is the last common version tracked by Unison that was equal on both devices.
• PySafe now asks for the passwords and displays a side by side comparison of differences between "desktop-db" and "N900-db". it can even merge things automatically, if there are no conflicting changes.
• The user taps the lists, indicating what changes are kept;
• PySafe then saves the results as the true merged file.
• Unison replicates the same new version on both devices
• The user lives happily forever, knowing that whatever and whenever she changes her pySafe db she will be sure that no changes will be lost.
