Yes, TV works in the same way. We direct customers to a web page with the Windows & Mac clients on it. They download, give us the ID / password and you're sorted.
We found TV won hands-down on cost once you start looking at the unattended client (eg for servers). The other products we looked at like LMI charged per unattended client. A single channel for LMI Rescue was costing us something like £60/month (without any unattended clients), so our TV Corporate license isn't bad as a one off.
