I'm a huge proponent of using SQLite as an abstraction over a filesystem. One warning I will note though, is be aware that a SQLite database does not shrink unless you vacuum it (basically copies the data into a separate file and deletes the original). This is a manual operation you have to do at points where it makes sense within your application. So be careful with disk usage when just writing binary data and then deleting it.
