So far, so good.

Correct.

That depends. I don't know if it's "safe" to backup the InnoDB
tablespaces without shutting the server down. I suspect that it's not
because there is no way to force InnoDB to commit all logged
transactions. In practice it may not be a problem, but it could be.
I'll have to ask the InnoDB developer about that.
If the answer is "yes", then adding support to mysqlsnapshot should be
quite easy.
