TLS Client auth in Spark?

I haven’'t seen it yet in the client configs and I know that the wildfire setup makes reference to the a truststore which they say is used for server issues certificate bassed authentication, but is it currently possible to have Spark use a client cert as authentication as opposed to password auth?

So far the security between Spark and Wildfire has been a huge selling point in my org and they’'re not complaining. Just thought it might be nice to be able to go one better.

NOTE: I apologize if this has already been discussed or if docs exists for this. I haven’'t been able to find any, so links to docs about this are welcome.
