IP config versus Desktop client

Questions to those of you already set up. We want to distribute both the
Palm and CE device Desktop Synchronization Integration software to ALL my
desktops, whether there is a device or not attached. We allow staff to
connect personal devices AND we have Agency issued devices. We want to at
least recognize all devices attached to our network, possibly force
certain security policies against all devices. Can this be done? Is
there any issues doing this, or should I only distribute the correct sync
software to machines that actually attach a PDA?

Second question: If you configure a PDA to use the appropriate IP client,
can you also install the desktop sync agent and use it. For example, I
want to be able to control whether a software install goes directly to the
device, or whether it goes to the desktop the device sync's with. That
way I can control when and how it is installed.

Thanks
