I still think that my red chunks example still applies... Since I can differentiate between an MN and a Client by noting that one doesn't ever perform a TX and one does, there really is no mixing... Thus, I can aggregate the signatures that match each other to find the total value of the TX.
Ahh, I see where your hangup is now. You misunderstand how MNs work.
The masternode doesn't leave a trace on the transactions, there is no way to determine whether a tx was related to a masternode or not.
Essentially you are sending a 1 DRK output from a tainted address and get 1 DRK back to a different address, however it is in your wallet (but your wallet only exists in your client, it is not public, and old keys can be deleted). The masternode simply facilitates this transfer.
It's been stated several times that masternodes leave a lot more than a trace. It's one thing to misunderstand it, another to read it 50+ times from official outlets...
OTOH...
Whether or not my questions are answered satisfactorily is a factor of my own ability to understand. If I'm just too stupid to figure it out, at least it serves as an example to others who might, lols.
You do raise a valid concern in that how exactly the functionality works needs to be communicated better.
As for MNs leaving a trace or not, let me play around with some transactions and see how it works in practice. I need to think a bit. However I still am quite confident this is a non-issue, but I do want to figure out a much better way to articulate the process so anyone could understand it (let alone someone who has historically had a lot of confidence in darkcoin and only the best intentions -- you)
It looks like the much more complicated version of the underpants gnomes right now...
1 ) Steal underpants
2 ) ??
3 ) Wonder why I stole underpants
4 ) ??
5 ) Sniff underpants
6 ) ??
7 ) Be glad they're not men's underpants
8 ) ??
9) Wait, these aren't underpants at all!

Every single step of how ASICs mine and proofs work,e tc is described, we all know every tiny detail of how BTC works. DRK has a lot more going on and there's really no explanation... The diagrams over-simplify to the point that it it's mis-representative... Yes, it's a more complex topic, so explain instead of going all iMac. DRK isn't for noobs, really. We're introducing pre-requisites. You have to understand pure PoW first, then add in the other stuff. Don't just skip over it...
Right now MNs are described as the mixing system that doesn't actually mix anything, so, uh... No TXes, only sigs... What? How do you mix when you didn't mix? Whaaa...?
