It's possible that both the hosting[1] of apps and also inter-app communication[2] would be possible via IPFS.

Orchestration of the resources (CPU, memory, storage) to run API services would also be possible in a distribution manner if we can envision something like Kubernetes to manage workload allocation across compute hardware (smartphones?) and if there's a way for participating nodes to obtain container images and storage volumes (IPFS / Tahoe-LAFS?).

Signing and trust would still be an issue, particularly for container images and storage volumes.
