Bah. Good database design waits not for users manually editing things!
Plugins will no doubt adapt (or not notice, if they're using the add
and remove options functions).

That was my basic line of thought, yeah. The options table is nothing
more than key/value pairs tied to a blog_id. For MU, this also means
that options can be fully separated without wacky option naming

Pretty much any table you care to create is going to have some kind of
unique ID field. If it then contains key/value pairs, it can fit into
this meta table design, as long as it also has a unique meta_type. The
meta_type could even be as simple as the name of the other table that
the meta_id is referring to.
