There is a small group of people working on getting bill 2099 pushed through the legislature. It will of course not go anywhere this session, but it should make progress in 2012.
For those that want to help, there is an AR-15.com forum member that is making a list of people so they can divide up duties to ensure everything gets done in an efficient manner. Look at this thread and contact the forum member by the name of bigscrun.
The best thing anyone can do right now is getting to know your Representatives and Senator. Write to them (not e-mail) and ask to meet with them in the future about the bill. You do not have to give specifics when you write, but ask them when it would be convenient to meet with them. If there are others who want to meet about the SBS/SBR bill, get together and meet your Rep as a team.
