Pt. 2 Gun ban, what may happen

I read a lot of blogs, news, history and I get emails and there is a lot of speculation about a possible gun ban and how it would go down and what the reaction would be. I could tell some did not think by blog yesterday was serious and it was partially poking fun but bottom line is nobody has a clue exactly what will happen.
I have no doubt that the left seeks to delete the Second Amendment from the Constitution. I also try not to get too caught up in a lot of hype but use past history to get a feel for where we are headed.
I do think there is a lot of hype and as much as I despise the liberals for "not letting a good crisis go to waste" there are also those who seek to profit from a situation like this. You have all received the emails telling you all your guns will be banned by next month if you don't send them $29.95 (or any other amount) for them to fight it or to send a fax to your congressman.
Don't get me wrong I am 100% against ANY and ALL gun laws they are unconstitutional and should be repealed  but lets take a look at past history.
1934, the National Firearms Act heavily regulated and registered fully auto weapons
Gun Control Act of 1968,  it stopped the ordering of modern weapons through the mail among other things. Interesting note this was a big reform and a backlash to the Kennedy assassination in 1963, it took 5 years to hash this out.
Brady Handgun Act, 1993 this included the requirement to do background checks for handgun purchases.
Federal Assault Weapons Ban 1994-2004, banned high cap magazines, and evil features like folding stocks, bayonet lugs and threaded muzzles.
In each of these cases there was complaining from those effected but I did not hear or read about widespread uprising so with more sheeple today than ever before I wonder what it would really be like.
After 0bama was first elected in 2008 there was a massive scare and gun sales went through the roof and he had control of both the House and Senate and could have banned all weapons like Australia did but nothing happened because I believe there was not enough votes even within the Democrat party to do it and I still don't think they have the votes to get a wide sweeping ban especially considering the Democrats don't control the House. Just my gut feeling.
 An all out ban on weapons would be a nightmare to enforce. To get an idea, the drug war is a huge problem, just think how bad it would be if there was actually a constitutional amendment that said "The right of the people to have and use drugs shall not be infringed"
