What solutions are available for publishing contacts to all users? (incl. mobile phones)

No need to re-invent the wheel, found this elegant solution over at petri.co.il:

# usage: Disable-User [accountname] [enable/disable]

function get-dn ($SAMName)    {
    $root = [ADSI]''
     $searcher = new-object System.DirectoryServices.DirectorySearcher($root)
    $searcher.filter = "(&(objectClass=user)(sAMAccountName= $SAMName))"
    $user = $searcher.findall()

    if ($user.count -gt 1)      {     
            $count = 0
                foreach($i in $user)            { 
            write-host $count ": " $i.path 
                    $count = $count + 1
                }

            $selection = Read-Host "Please select item: "
        return $user[$selection].path

          }      else      { 
          return $user[0].path
          }
}

$Name = $args[0]
$status = $args[1]
$path = get-dn $Name

if ($path -ne $null)    {

    "'" + $path + "'"  
    if ($status -match "enable")     {
        # Enable the account
        $account=[ADSI]$path
        $account.psbase.invokeset("AccountDisabled", "False")
        $account.setinfo()
        Set-Mailbox "$Name" -HiddenFromAddressListsEnabled $False
    }    else    {
        # Disable the account
        $account=[ADSI]$path
        $account.psbase.invokeset("AccountDisabled", "True")
        $account.setinfo()
        Set-Mailbox "$Name" -HiddenFromAddressListsEnabled $True
    }
}    else    {
    write-host "No user account found!" -foregroundcolor white -backgroundcolor red
}

Save it as Disable-User.ps1 and run .\Disable-User.ps1 SAMaccountname disable

the only solution I have found is using the mailContact method. This is a hassle because you then have two lists, AD users and then the new contacts. There is no need to export the Domino address book as all the users are already in AD and have the mail attribute set. So what I did is created a powershell script that reads AD and creates a new contact for each AD user. It will remove existing contacts before adding the new one to keep the list upto date. I am going to run this on a schedule. Its not the best way but it seems to be the only way to do this.
