VCardIO for GroupDAV operations

[GoogleCodeExporter]

First of all: Thanks for the great work! VCardIO is the only Android-App
that I could find that would allow me to import VCards without adding my
address book to Google Mail.

However, I'm using my address book on more than one devices (that would be
my mobile and my laptop for now), so I'd like to keep them in sync (still
without Google Mail). GroupDAV is an easy way to do this that is already
supported by many Desktop-PIM-Products.

So I was wondering: Would you be interested in adding GroupDAV-Sync-Support
to VCard IO? If you don't want to integrate GroupDAV support into VCard IO
directly, is there a way to access the phones contact database through
VCard IO?

I have previously tried to build such an App from scratch, but got stuck on
the vcard-parsing-part. Thus, I'd like to try and integrate the
GroupDAV-parts with VCard IO.

I'm envisioning the following:

1) Add Support for importing from/exporting to a GroupDAV share

2) Add Support for a 2-way-diff (take two VCards of the same object and
incorporate the changes in each into the other) - I have previous work on
this. The tricky part is mapping attributes between Android and VCards, but
you probably know this already.

So, what's your opinion on this?
