Topic: Asset Model or type custom fields

Our company was looking to implement custom properties based on the type of asset.  I was looking around your sites and found a perfect example of something someone had written up.  I am just wondering if you can give me a better idea of what time frame we are looking at this for implementation and what stage of the process it is at, if any.
