Are options 60 and 61 bi-directional?

[Doug Barton]

Apologies in advance if this is a silly question, but I can't seem to 
find an authoritative statement. (Perhaps it's such an obvious issue 
that no one thought to make one.)

I always thought that options 60 and 61 were client -> server only. Am I 
wrong in that belief, or can the server send those options to the 
client? And if so, what would the client do with it?

Thanks,

Doug
