Hi all, I was playing with raw transactions just for fun, so I managed to generate a transaction between two wallets of mine of 5640 satoshi (the minimum amount which should be accepted by the network), without fees.
I finally broadcasted the transaction and all seems fine with the transaction itself.

Now, as it was predictable, the transaction doesn't get confirmed. It was broadcasted 48 hours ago. What I want to ask to someone more experienced than me is:

1) is there at all the possibility that the transaction will eventually be confirmed?
2) in the meanwhile, that tiny btc amount is someway freezed? Am I able to spend them again (i.e. to use them from the same "unspent output" I picked them in order to build a new transaction)? Or they already belong to the new address and I will be able to spend them only from that new address and only if and when the transaction will be confirmed?
3) does the transaction priority would have changed, even minimally, if I had included a 1 satoshi fee in the transaction? or the amount of fees is not important until they don't reach the "suggested" value?

Thanks
