Trying to understand FTP

To help myself (and others!!) understand FTP so I can get my head
around the need for ip_conntrack_ftp when using IPTables, I've posted
a thinga-me-bob on how FTP works:

Any comments, like if I've got it totally wrong, would be appreciated.

This is the definitive document, the best I've seen so far on this topic:

I am still studying this myself, but I think the answer is in here.
