A few things I've noticed:

1. The deb needs to list some dependencies, like python2.5-gtk2, python2.5-cairo, python2.5-hildon
2. All the input fields are set to auto-capitialise, which is wrong for username (and really hostname too).
3. The password entry box isn't a password field, so it both auto-capitalises (see above) and shows it in clear-text.

Finally, whenever I set it up and clicked the button, the app froze; I was asked if I wanted to kill it, and eventually it unfroze and did nothing. Running it from the terminal didn't show any errors.

However, running:

...worked fine.
