Cap'n Proto is essentially a sub-project of Sandstorm. Lately, there hasn't been a whole lot of churn in Cap'n Proto land as it is doing what we need it to do. That said, there are a few features I'm becoming increasingly eager to implement, probably later this year. The biggest one is three-party handoff: when Alice holds a capability pointing towards Carol and sends that capability to Bob, then Bob should form a direct connection to Carol rather than proxy requests through Alice. This will be important for improving scalability of the cluster version of Sandstorm, although at the moment it's getting along fine without it. But yeah, Sandstorm uses Cap'n Proto extensively, so if there's no updates to Cap'n Proto, it's because its biggest user hasn't seen a need to make many changes. :)
