Abstract
A portable device may be roamed from one host to another. In one example, the portable device stores software that is to be executed by a host. The host may maintain a policy that governs which software may be executed on the host. When the portable device is connected to a host, the host checks the software version installed on the guest to determine whether that software version is compatible with the host's policy. If the guest's software does not comply with the host's policy, then the host installs a compatible version. If the guest's version complies with the policy and is newer than the host's version, then the host copies the guest's version to the host and propagates it to other guests. In this way, newer versions of software propagate between hosts and guests, while also respecting specific execution policies of the various hosts.
