Running SQLite without a database file creates an in-memory database. Using the .dump command will dump that in-memory DB to a SQL file that can then be re-read into a file-backed database (or back into a memory database), just as Mark asked about. Of course, I assume Mark wants to do this via code.
If you want to map the work - save - work pattern I would still prefer the temporary file solution. On first save rename / move the database to the proper location. If you cross filesystem boundaries (so you acutally have to copy the data) create an online backup to the proper location, so the user can continue working on the database.

SQLite Backup API, It cannot be used to copy data to or from in-memory databases. If a power failure or operating system failure occurs while copying the database file the backup Function sqlite3_backup_init() is called to create an sqlite3_backup object to copy data between the two databases (either from a file and into the in-memory database, or vice-versa). Function sqlite3_backup_step() is called with a parameter of -1 to copy the entire source database to the destination.
In-Memory Databases, An SQLite database is normally stored in a single ordinary disk file. However, in certain circumstances, the database might be stored in memory. The most common way to force an SQLite database to exist purely in memory is to open the database using the special filename ':memory:'. SQLite in-memory databases are databases stored entirely in memory, not on disk. Use the special data source filename :memory: to create an in-memory database. When the connection is closed, the database is deleted. When using :memory:, each connection creates its own database. Data Source=:memory: Shareable in-memory databases
