There are states that share reciprocity agreements, meaning you may obtain a license without having to take a class or a test.

MD has reciprocity with PA and Oklahoma. 

@Mark Gallagher  not really I got my Brokers RE license in MS.. and it was like taking a drivers test a little pamphlet show up at the state department..  13 total questions  I got 11 correct and there you go newly minted broker in MS.. now to be fair that was a reciprocal with my California brokers license .. someone starting from scratch has to take the federal part and I suspect the state of MS part is more than 13 questions.. but you know you play the hand your dealt.

I understand that nothing is free and would be willing to reciprocate any efforts in helping me get on my feet.

Is there any difference between reciprocity and mutual recognition and is it true California, being the big state it is in itself like its own country, has ZERO reciprocity with all other states?!

Here most of the State is connected thru reciprocity to the other MLS's.

Just connect with an investor friendly agent and reciprocate by referring unwanted leads to them when it's appropriate.

And if anyone has tech questions happy to help/answer/reciprocate!

Very fortunately Pennsylvania has reciprocity with NY as far as RE Broker licensure is concerned.

I am not saying you have to become good buddies, but it is important that there is a sense of respect and reciprocity.
