Ah, that's sort of what I thought, but it turns out that there isn't
anything in the spec that says that. And, in speaking to Josh, there's
valid reasons not to require this at all! A server might be configured
to send these options always or for a certain "class" of clients
(however that class is determined).

	Isn't that the point of 124/125?  The client sends in 124 with
all of the vendor IDs it's interested in/supports, and a 3925 aware
server would key off of that (instead of 60) to choose what to fill 125
with?

		One thing that isn't as clear as it could be in RFC 3925
is how a client communication interested in a certain vendor option set.
Part of the reason for this is that it really is up to each vendor to
determine that. But that does make it more difficult for server vendors
to provide appropriate triggers. Likely most servers will require you to
classify the incoming request in some way and then the options
configured for that class are returned. A common trigger for this might
be option 60.
