It's true that it'll need more munging, but since we have a neat way to
upgrade between database schema versions, I don't see a huge problem
with doing adding a new column to the database if it is otherwise the
best solution.

Are there occasions where we would want to fetch all nodes from the
database in one go? In that case, having multiple tables, one per
'domain' would just be inconvenient.

Are there any other similar considerations? Differing ACLs maybe? The
column method certainly feels cleaner.
