Hello,

 First of all, congratulations to all involved! Helix is a great project and 
seems to have a bright future, I hope to have time to contribute to it 
myself... but for now I'm just a user with a few questions about it...

 1. I'm using a LeaderStandby in order to build a single global lock on my 
cluster, it works as expected.. but in order to release the lock I have to put 
the current leader in standby... I could achieve this by disabling the current 
instance. It works, but doing this I loose (at least seems to be) the ability 
to send/receive user defined messages. I'd like to know if it's possible to, 
via an api call, force a transition from Leader to Standby without disable an 
instance.

 2. I've been taking a quick look on Helix codebase, more specific on ZooKeeper 
usage. Seems that you're using ZooKeeper as a default implementation, but Helix 
architecture is not tied to it, right? I'm asking this, because I'm interested 
to implement (in a near future) a different backend (Infinispan).

That's it for now...  thanks in advance.

Cheers,
