Hello Everyone,

I'm working on implementing CalDav support for Maemo's inbuilt calendar and I need a little help and a few ideas.
I've managed to get libcaldav[1] and libical[2] compiled and working and can interact with an online caldav calendar server. It's not fully tested yet though, so I can't say it all works.
Next, I plan to write code translates between libcaldav/libical and Maemo's Calendar-backend[3]. This seems to be a simple yet non-trivial task.
Before I start, I was just wondering about the overall architecture of what I'm doing, and I would like some input.

How should I structure the whole thing?

The calendar UI is closed, as far as I know.

1]

I could compile my code into a sort of daemon, write a separate GUI (that goes into the settings app) which stores user settings (Calendar URLS, usernames and passwords) etc. and interacts with the daemon.

Pros:
1. Separation between the backend caldav-calendar interaction and the frontend UI and settings.
2. People are free to implement their own GUIs or interact with the backend CalDav programmatically etc.

Cons:
1. Adds a lot more complexity, such as communication between the two separate parts.

OR

2]

Write a monolithic app that includes the backend CalDav stuff, the GUI and settings etc.

Pros:
1. Simple to implement

Cons:
1. It isn't a modular approach. Combines two essentially unrelated tasks.

Any ideas, inputs, comments? This is the first time I'm programming anything for the Maemo platform and I'd like to do it right
