public secret and public radius server. Is it secure?

[vertito]

My question is :
- What can a malicious user can do with the secret? Can it alter accounting
and other things? (chillispot uses chap auth-type)

one is spell it out and try rumble it so he forms a new word from it

- Is there a way of maintaining a per hotspot secret with dynamic ip
addresses?

yes. check client and clients.conf relationship
