Hi there,
>From what I've read (not implemented) you can establish this
by configuring mapping agents on HUB router, in which case
the RP-candidate can be any of the spokes. This has to do with
Auto-RP message distribution. So as long as you use nbma-mode and
have the agents on the HUB router it should work.

John,cliff,
I also tried multicast over frame relay.
It worked fine when Hub router is configured as RP.
But when one of the spoke router is configured as RP
I am unable to ping from spoke to spoke.
Could anybody please clarify whether RP should be always
be at Hub for multicast to work over frame ????
Thanks

John,
Did you enter ip pim nbma-mode on the hub, also ensure that the command
ip pim sparse-mode -or- ip pim dense-mode is enable on each
participating interface.
Have you had any success with AppleTalk running over ASYNC? So far I've
tried using the client-mode command on each side. Enabled a appletalk
virtual-net with no success. Removed the configs and attemped to use an
cable-range and a zone like any other interface with no success. If I
put ip addresses on the point2point link and enable EIGRP I am able to
ping across the ASYNC. So I know my cable is good. Any suggestions?
