OSPF NBMA Question

Question for the gurus...

How can I get the spoke routers in a hub & spoke frame
relay to peer with each other based on this
configuration:

       /R2(spoke)
      /
R1(hub)
      \
       \R5(spoke)

R1:
interface Serial3/0.100 multipoint
 ip address 10.100.10.1 255.255.255.248
 ip ospf network broadcast
 no arp frame-relay
 frame-relay map ip 10.100.10.2 102 broadcast
 frame-relay map ip 10.100.10.5 105 broadcast
 no frame-relay inverse-arp
!
router ospf 100
 router-id 10.100.100.1
 network 10.100.0.0 0.0.255.255 area 0

R2:
interface Serial4/0.201 point-to-point
 ip address 10.100.10.2 255.255.255.248
 ip ospf network broadcast
 ip ospf priority 0
 frame-relay interface-dlci 201
!
router ospf 100
 router-id 10.100.100.2
 network 10.100.0.0 0.0.255.255 area 0

R5:
interface Serial4/0.501 point-to-point
 ip address 10.100.10.5 255.255.255.248
 ip ospf network broadcast
 ip ospf priority 0
 frame-relay interface-dlci 501
!
router ospf 100
 router-id 10.100.100.5
 network 10.100.0.0 0.0.255.255 area 0

The spokes are peering with the hub but not with each
other.

router1#show ip ospf neigh

Neighbor ID Pri State Dead Time
Address Interface
10.100.100.2 0 FULL/DROTHER 00:00:36
10.100.10.2 Serial3/0.100
10.100.100.5 0 FULL/DROTHER 00:00:35
10.100.10.5 Serial3/0.100

Also, the spokes can ping each other just fine. Does
this have to do with the fact that the spoke routers
are using the "point-to-point" sub-interface type?
