WMI cmdlets in CTP

I've been looking at the new WMI cmdlets in the CTP - Invoke-WMIMethod and
Set-WMIInstance

Invoke-WmiMethod -Class Win32_process -Name Create -ArgumentList calc.exe

works exactly as you would expect it to

I then moved on to trying the DNS namespace and get errors about the methods
don't exist - when I've used them via V1 syntax.

Couple of questions:

1) If a method is only accessible using a psbase construction eg

$rec = Get-WmiObject -ComputerName DC02 -Namespace 'root\MicrosoftDNS'
-Class MicrosoftDNS_AType -Filter "IPAddress = '192.168.172.20'"
$rec.psbase.Delete()

can I access it via Invoke-WMIMethod

2) Are Invoke-WMIMethod and Set-WMIInstance limied in the namespaces they
can access? Don't see why they should be bu tthey don't seem to like the
MicrosoftDNS namespace

3) if I have multipe arguments for the -ArgumentList parameter in
Invoke-WMIMethod do I need to create a hash table as in Set-WMIInstance.

4) Does the -Flag parameter in Set-WMIInstance actually exist - its in the
documemtation but I get an error saying it doesn't exist when I try to use it

#4 may be just an example of a upcoming feature that was slipped into
the documentation ahead of it actually being programmed in.

I was told shortly after that the questions had been forwarded off to
the Microsoft WMI team.

No news otherwise...
