Bitcoin Plus
Bitcoin Plus is a Browser Bitcoin Miner written in Java. The miner is initiated by the end user, but is also embeddable in webpages, much like Bitp.it
Overview
The user registers an account, then is prompted to start mining. Mining is paid on a pay-per-share basis, with 3% taken by the pool operators. The site suggests that users invite their friends to mine with them, and allows users to embed java miners on their websites to create a Distributed Miner.
The UI provides features which seem to be exclusive to the site, such as a prediction of the time it will take to calculate one share.
