The "photo app" market is a zombie apocalyptic wasteland of failed and undead software. I don't want to get burned again, either, so:

1) There's a corporate mandate to open-source PhotoStructure for Desktop in the event of business closure.

2) Your library consists of industry-standard files. If you choose to do so, your originals are copied into a standard YYYY/YYYY-mm-dd/ folder hierarchy. XMP sidecars are added to hold inferred or novel metadata and store nondestructive edits, like rotation. A SQLite db (with commented schema! it's pretty, honest!) holds asset-file-tag relationships, albums, and other non-file metadata.

3) It's just me, and I love open source, so if I can get to the point where my licensing stream pays for food and shelter, I can open source then.
