Not at all - ACK from me, fwiw. Any attempt at a double spend should be
shouted from the housetops.
What Miners should do with that is still up for debate, it seems. My
opinion is that they should hold on and attempt to confirm the first,
letting it go only if a conflicting transaction is mined

I've been wondering why a blockchain is necessary at all. Ripple doesn't
have one (I haven't looked closely at their implementation but it seems

That's good - what I had taken away from the replace-by-fee discussions was
that it was finally decided.
My opinion is that we should be doing what we can to make 0-confs as
reliable as possible - which will always be 'not very', but a solid system
to notify on attempted double-spends is a good
A part of my reason for sending this email was a quick discussion I had
