just a random thought:
In an MMORPG, you always create your character first.. you change hair colour, face shape, height, eye colour etc etc etc.. after all these combinations your "appearance" can be recorded as just a string of characters "EDfewe232DFwewfehjhti" is my avatars appearance.
Just something else that can be stored... there could be a website designed where you create your character then copy and paste your "appearance code" into your name's value..
e.g. ch/snailbrain"EDfewe232DFwewfehjhti"
useless at the moment, just a thought

-- (you could just save that on an open website though i guess, but it could be in your id tag :d)

Any fees need to go back to the miners.... it shouldn't be expensive to create a name... but should be expensive to spam the network..
The 0.01 fee for name_new should go back to the miners when the "name" expires.. if this would be possible.
Higher Cost for shorter names is good... if we used namecoin for some system where human readable names isn't too important.. e.g. login/snailbrain21341fdsf then shorter names being expensive and longer names being free (or almost free) seems good.

The coins where domains are attached are currently 0.01NMC, but there's nothing in the code that validates that amount. It can be as low as 10^-8. I will change to 10^-8 in the near future.
In the current system, registration fees are reduced by 50% about every 3 months. There is no lower limit, so the fees will go to zero after a few years. If the value of NMC grows faster than that, then indeed there is an issue.
I will consider speeding up the registration fees decrease, probably to 2x per month, to try to match bitcoin/namecoin growth rates. This will be done at the same time that the switch to joint BTC/NMC mining is done.
The eventual plan was for new names to be free.... apart from "data usage", standard transaction fees are enough?
NMC/KB is good.. but registering names alone shouldn't be too expensive. Changing the data costs 0.005nmc atm?
