Count me in for Shadow realm lairs!!! I'd love for them to move around, hard to find for others or a portal/summon only way of getting into your SR home; except if you are 'dead'. No access to the dead. I love the original idea of them requiring B/W decor due to the nature of the realm.
A thought to ponder, we do have apartments, dwellings, shops, large estates in private territories (like cedar court, trailer parks). I can see the need for more of these after beta because eventually, like us, the newbies will want a piece of their own land too.
Other ideas:
- Part time residence. Like university dorms for $3-5 Karma a month for a 2 room place.
- Avatar Clothing
- Naming vehicle or Change Model (kinda like the custom weapon option)
- New vehicle; golf cart - drives slower then regular vehicles (ex: cheaper than a car + smaller gas tank

)
- NPC Security guards for businesses or bouncers at bars. [They would have to be super strong for someone to kill off in order to disable cameras or alarms? Like a mini game]
- Remove someone from an invite list (I know there's a rit for it, but it was a thought)
- Clear a bounty above X# of violations, allowed once every 6 months for 10 Karma?
- New Community; Golf course territory? with luxury homes.
- Own public park (4 square area-literally)
- Rent public park ground for $1-5 Karma w/ RP chat space (includes: invite list for private party & no grid attacks (rp is fine); Someone would have to call a park commissioner(or reserve the space on crownet appointment list) to rent the space for use for an exact date and period of time ahead of time.
- Street names! "Buy a Road" or "Park or Bridge" for Karma?? sounds fun. [would drive map folks nuts though]
- Ski lodges! - It does snow in Canada. ;)
