Hi,
I don’t know about the current deployment plan for Snowflake, but I can point you to the relevant parts of the git repository:

Tor Browser 8 Alpha includes the Snowflake PT as it comes near a final release, the adoption and usage of the Snowflake PT will continue to rise. I now have the following questions...
- Will a command line tool like an obfs4proxy come out so those of us with infrastructure can run high capacity snowflake bridges.
Like Meek, Snowflake is a 3-component transport:
User -> Proxy -> Bridge
The command-line Snowflake Proxy is here:
https://gitweb.torproject.org/pluggable-transports/snowflake.git/tree/proxy-...
It will automatically be distributed to users using the same broker.
I am not sure if the default broker is the broker used by TBB users. You should ask tbb-dev@lists.torproject.org , or copy the configuration from the snowflake Proxy website.
The Snowflake Bridge pluggable transport is here: https://gitweb.torproject.org/pluggable-transports/snowflake.git/tree/server
However, your bridge needs to be distributed to users: * if you want to run a private bridge, just tell those users yourself * there is no automatic distribution, because BridgeDB does not support snowflake: https://bridges.torproject.org/options * if you want to run a TBB bridge, write to: tbb-dev@lists.torproject.org
- Is the goal to replace OBFS4 with Snowflake or will they continue to co-exist?
I’m not sure that any decisions have been made yet.
But my understanding is that Meek won’t work soon, because many sites don’t support domain fronting.
So I think the goals are: * replace Meek with Snowflake * replace obfs4 with some better protocol
- How does Snowflake attempt to obfuscate, if at all it's traffic? How strong is the cryptography compared to obfs4proxy
Snowflake’s components use TLS for point-to-point connections.
Inside Snowflake, client to relay connections have all the standard tor encryption.
I don’t know what obfuscation Snowflake uses, but you could read the code or documentation, and let us know. (Or wait for someone else to respond.)
