I have no experience with Mobile IP, but I'm not sure if it is supposed 
to handle multicast anyway (?) rather than just unicast.

I'd assume the delay is due to the fact that the laptop does not send an 
IGMP/MLD membership report as soon as it gets its new connectivity 
(plus, maybe, some delay on the multicast router).
