IIRC, multiple writers in SQLite is supported, their writes will just be serialized. What you don't have is concurrent writes. But, given SQLite writes are so fast, in practices it's not really a big deal.
If you haven't used SQLite in a real project with heavy writes, I'd say you do it. SQLite is WAY more powerful than people tend to think of it.
