It depends on what kind of remote management you're looking at doing.
You don't have to install PowerShell on the remote system to use WMI or

For example, apparently this tool can also deploy PowerShell: http://www.specopssoft.com/powershell/
I'm not sure if it is a limitation of their enterprise version (they
have a free version and one you must pay for).
