There are definitely many ways of installing and updating an OSGi framework. BundleContext gives you the low level API you need, and it's not too hard to create your own. Pretty soon you might end up with something that's similar to Apache Felix FileInstall that hot deploys things from a local folder. Or you might want to use the OBR client to pull in bundles and their dependencies.
However, if you are looking for something that you can use in bigger production environments, that installs updates transactionally, that keeps history so you can quickly go back to older versions, etc. Then ACE might be a project to look at (and participate in).
