I am curious how long it will take to send and receive coins when going through 8 MNs. Seeing RC4 live should answer that.
The Darkcoin client will now store pre-mixed, denominated Darkcoins in the users wallet, to be used instantly at any time the user desires. The mixing and denomination process is seamless, automatic, and requires no intervention on the part of the user. The 10 DRK limit previously in place with Darksend v1 will be permanently removed.
