DICE's Mikael Kalms has explained over on the EA forums why the company will not allow for the use of home servers with Battlefield 3.
According to Kalms' post on the game servers, the decision to only allow Ranked Server Provider companies to run a server, is due to the ease of providing support.
"The game server machines themselves will be run by a number of Ranked Server Provider (RSP) companies," he said. "We do not allow other companies to run game servers, or for other people to run game servers from home.
"We try to strike a balance where there are game servers available across the globe, while still keeping the number of RSPs at a level where we can offer reasonable support to each individual company. Since we prefer to work with larger hosting companies, and we focus on countries where we have a larger player base, there will not be game servers available in every country on the planet."
The list of RSPs which will run BF3 game servers at launch is not ready yet. Once all is in place, and announcement will be made.
