How can I quickly find a blog's ID number?

I am looking for an easy way to copy a blog to give to a leaving student. Currently, we use the Site Sucker app to suck the blog off the web into a local folder, but are exploring other options. Export and import to another WP site is problematic due to us being based in China.

One way we thought of was to copy the blog directory in it's entirety, but we can't find the blog id to know which one to copy. How can we quickly find the ID of a blog in our Multi Site? Is there another way you'd recommend to get the blog to students that works with our situation?
