I have an in-memory SQLite database which I want to serialize and send to another computer. Is this possible without writing the database out to disk and reading the file from there?

You could use the online backup API to transfer the in-memory database, to a file-based database created in shared memory (for Linux, in /dev/shm for instance) avoiding the disk operations. Then this pseudo-file is transferred to the remote host (still put in /dev/shm), and the online load API is used to transfer from the file-based database, to your target in-memory database.
See:
http://www.sqlite.org/backup.html
http://www.sqlite.org/c3ref/backup_finish.html
AFAIK, there is no API to perform online/load without intermediate databases.
