Detailed Description

Feed writer class.

how to make it "secure" alternative 1:

hash for all objects
feature "mail me rss link"
link includes ref id, user id, combined hash (kind of password)
combined hash = hash(user hash + object hash)
ilias checks whether ref id / user id / combined hash match
