I'm looking forward to using Docker (or another container format) for reproducible computational work. Now, it's still somewhat difficult to keep versions of programs in sync on clusters (even using environment modules). It will be really nice when we can store the application environment as a container and be able to pull that configuration off the shelf to repeat an experiment/analysis. Unfortunately, that use-case usually happens on multi-tenant HPC clusters, where we can't use Docker yet until the security issues are figured out (or we can get a solid and standard micro VM for running containers). Job scheduling is also a non-trivial issue.
