Support of multi-session discs #76

Hi all.

I understand that dvdisaster works by augmenting an image with error correction data, which is meant to be burned on the disc all at once.

I was wondering if this approach could be extended to work also on a multi-session disc, i.e., you write a first session made of the data and its error correction data, then later add further sessions of the same kind until the disc is full.

In this way, a single disc could be used as storage for an automatically backup system, which would, for example, add new data daily until the disc becomes full.

Is this "theoretically" possible?

Thanks, Giovanni
