Something to look forward to on Testnet at some point .. hopefully soon
edit : specially looking forward to the syncing headers first that bitcoin got implemented with version 0.10, should make syncing really fast for Dash
From bitcoin version 0.10 release changes : https://bitcoin.org/en/release/v0.10.0
Bitcoin Core now uses ‘headers-first synchronization’. This means that we first ask peers for block headers (a total of 27 megabytes, as of December 2014) and validate those. In a second stage, when the headers have been discovered, we download the blocks. However, as we already know about the whole chain in advance, the blocks can be downloaded in parallel from all available peers.
