WinRM Configuration on Windows 2008R2

We have recently been given the green light to use Powershell.
Most of our servers are running 2008 r2 and we want to use powershell cmdlets when possible vs wmi calls from powershell.
But we need to configure WinRM on the target servers which many are production.
Is there an impact, issue, pitfall to setting this up.
I will have to make a very detailed request for this and need to have all my ducks in a row to field any questions or push back that may come.

Any advise is greatly welcomed
Thanking everyone in advance

you might as well get the latest windows management framework.  Will require a reboot.  on each machine run from an elevated command prompt 'winrm -quickconfig'

We are starting to rollout .net 4.5 on our production servers so seems as a well worth add on.
There are a few servers that we cant because we have an old version of biztalk.

But regardless, i still need to prepare a well defined argument to get upper mgmt to approve this change and the server reboots are a hard sell specially in health care.

You can make the argument that any avenue for access is a vulnerability, but beyond that I see no issue with allowing this.  If you're concerned about securing the traffic between machines you can set it up to use HTTPS (TCP 5986).  Do you already allow remote WMI queries or PsExec?

There's potential for great gains when using PowerShell Remoting, particularly with fan-out processes.  It could reduce the run-time of a script drastically when querying many remote machines.  Particularly for remote registry work, using PS Remoting is a great approach as your code doesn't have to differ from how you would access it locally.

I'll share some links which I think are good reading.
