user-class

[Matt Pascoe]

One thing you could try is the following statement:
append dhcp-parameter-request-list 1,3,6,12,15,66,208;

It will add the specified dhcp options to the response that the server gives
to the client.  This allows you to send things to the client even if the
client did not ask for it.  Obviously the client has to be in a position to
do something with the information it is sent from the server however.
