I mean if I have address A and no ethers on it.
And I will construct valid tx & and sign it with my privkey.
Can I send this raw signed tx to my friend with address B, and he will push it to the network.
He need to sign it, and gas will be taken from his B address, but in contract
msg.sender will be set as address A, who initially signed this tx.
Is possible scenario like above? I assume it is not at this moment. But do Vitalik`s team want to implement something like that to be possible?
