"Configurable hierarchical/inheriting/prioritized/whatever-your-favorite-word-is blacklists and whitelists (via OddItem groups)"

I can't seem to get this working. I think i must be missing some key point about how to connect user groups (permissions) with OddItem groups (for use with OddGive). I'm hoping you can point out my error, or let me know if OddGive doesn't support this functionality (and recommend another plugin?).

Here is my goal:

1. I have 4 groups of users : default (no PermissionsBukkit group), registered (PermissionsBukkit group), guide (PermissionsBukkit group), and admin (PermissionsBukkit group and op)
2. I want default to not be able to /i or /give anything
3. I want registered to be able to /i only stone, dirt, cobblestone, wood, sand, and gravel. no /give
4. I want guide to be able to /i stone, dirt, cobblestone, wood, sand, gravel, PLUS ipick. and i want them to be able to /give these same items to anyone, even giving ipick to registered users
5. I want admin to be able to /i or /give anyone anything

Problems:

1. I don't know how to connect the superperms user groups with oddgive + odditem, to provide group based whitelisting. If this isn't possible and I need to define users/groups in OddItem itself, i don't see a way to specify users there.
2. with this config 'as is', all users can summon the items listed in OddItem.yml. I had to remove the items from this list that I don't want my users summoning. I kept a backup copy so I can add them back once I have the group restrictions in place.
3. when using /og list, users always see [] for the list of things they can summon, even though they can summon stone, dirt, cobblestone, wood, sand, and gravel, so i'd expect to see '[stone, dirt, cobblestone, wood, sand, gravel]'

Things that do work:

1. superperms + oddgive/odditem permissions as far as allowing commands like /i , /g , /i0 works fine. just not any whitelisting based on groups

Why I want to do this: I was able to do all of these things with SpawnList mod (which does not work with superperms and appears to be currently unsupported). I'm trying to replace SpawnList with OddGive + OddItem. This is a SMP Survivial server. We allow normal users to summon standard building materials only, to discourage 'strip mining'. We have helper 'guides' who can summon back essential gear for players who have a bad lava/teleporter/corpse run/creeper incident- so they need to be able to /give things that the target user can't /i himself. And we have admins who are 'godlike'.

OddGive config:

defaultQuantity: 1
blacklist: false

OddItem config:

comparator: r

    oddtransport:

                priority: 1
        items:
        - rock
        - dirt
        - cobblestone
        - wood
        - gravel
        - sand
items:
    '1':
    - rock
    - smoothrock
    - smoothstone
    - stone
    - 1
    '3':
    - dirt
    - 3
    '4':
    - cob
    - cobble
    - cobblestone
    - 3
    '5':
    - plank
    - wood
    - 5
    '12':
    - sand
    - 12
    '13':

    - 13

PermissionsBukkit config (real names replaced with TestUserX:

users:
    TestUser1:
        groups:
        - registered
    TestUser2:
        groups:
        - guide
    TestUser3:
        groups:
        - admin
groups:
    default:
        permissions:
            oddgive.give.bypass: false
            oddgive.i0.other: false
            odditem: false
            oddgive: false
    registered:
        permissions:
            oddgive: true
            oddgive.i: true
            oddgive.list: true
        inheritance:
        - default
    guide:
        permissions:
            oddgive.give: true
        inheritance:
        - registered
    admin:
        permissions:
        inheritance:
        - guide

But, how do I connect OddItem group 'oddtransport' to superperms group 'registered'? And, how to define other OddItem groups that inherit?

thanks much & I appreciate the assistance in advance.
