Maybe this can help. When you create a filestream there is an FileShare option. If you set it to ReadWrite, multiple processes can open that file

$fsMain = [System.IO.File]::Open("C:\stack\out.txt", "Open", "ReadWrite", "ReadWrite")
$fsReadOnly = [System.IO.File]::Open("C:\stack\out.txt", "Open", "Read", "ReadWrite")

Write-Host ("fsMain:  CanRead=" + $fsMain.CanRead + ", CanWrite=" + $fsMain.CanWrite)
Write-Host ("fsReadOnly:  CanRead= " + $fsReadOnly.CanRead + ", CanWrite=" + $fsReadOnly.CanWrite)

$fsMain.Close()
$fsReadOnly.Close()
