After a months of crazy mining you decide to find which of the coins have "dev" and which "copyDEV".
I think the next clients update, will bring the testnet to all coins from you Blegh-list.
And what?
What would be next - QR, UPNP ....
Search for tricksters needed before all became mine somethihg, but not after.
And from a technical point of view - all of these things is not so important,for now.
And implementing of them - is a trivial.
