How can I use PowerShell to make remote registry changes?

Question

I have tested the following PowerShell registry settings and it sets them correctly. Could someone show me the way to do this for a remote computer?

New-Item -itemType String HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\TrapConfiguration\Server0ps -Value "MY.DOMAIN.COM"
New-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\PermittedManagers -Name 1 -Value "whatever" 
Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ValidCommunities -Name "Hello" -Value 4
Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ValidCommunities -Name "There" -Value 8

Use this as example:

$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $computername ) 
        $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run",$true) 
        $regKey.SetValue("New_Valuename_String","New_Valuedata",[Microsoft.Win32.RegistryValueKind]::String) 

To create a new key you need use powershell remoting with invoke-command for new-item cmdlet.
