BigFix considers agents for cellphones and PDAs.

"BigFix, which develops software distribution, security and configuration technology for corporate endpoints in a client/server architecture, is looking at the development of agents for mobile phones and PDAs."

BigFix plans agents for hypervisors and cellphones.

"BigFix offers patch, software distribution, security configuration, asset-management, and power-management for servers, desktops, and laptops. It delivers these capabilities by deploying agents on the machines that are to be managed. BigFix CEO Dave Robbens said the agents' role is to carry out continual assessment of the host system’s compliance with corporate policy, both when connected to the network and not... there are plans to launch an agent for smart phones in February. The first mobile OS for which one will be available will be Windows Mobile (versions 5 and 6). The rationale behind this is obvious. Enterprise mobility is growing and extending beyond laptops into smart phones and PDAs, while the most vulnerable OS in such environments is the Microsoft offering."
