I really like the idea of the Advertisement banner, But i believe it would take time to develop such a plugin and it could create a mess for some users, There could a possibility if admins approve and (ad) before it goes live. But it would add extra burden on admins but indeed it would increase number of post as other users would try to complete posting for ads. If it's kept under control this could really be a great idea.
Other than, Points are just for giving out VPS, I believe adding some other things would effect the look of the forum!
