Alt Coins: Retargeting Difficulty at every Block

[fuzzbuzz]

I would like to follow all the alt coins that can retarget the difficulty at each block creation and then ask the question.

: is it possible for difficulty to adjust during a block

DigiShield re-targets a coin’s difficulty between every block or in the case of DigiByte & Dogecoin, every 60 seconds


Please list the types of retargeting projects available.

DigiShield
Kimoto Gravity Well


Why is this important? To counter Multipool operations.

I found this from Megacoins "Over 140+ Cryptocurrencies using the Kimoto Gravity Well! "
Wow. 
And how many using Digishield?

Only 1 or 2 ? But I prefer X11 , it's good enough for my rigs.
