Memcached rather than wordpress DB

I apologize if this isn’t the proper way to ask such a question (perhaps this is more of an enhancement request), but I’m wondering if there would be any way to utilize memcached / redis to store the geolocation cache rather than in the main wordpress database.

My server guys are saying that constantly writing to the db is causing some high load issues when there are a large number for concurrent visitors. They are recommending something more like memcached or redis for storing and retrieving the user ip/location information.
