How do I get directory depth in PowerShell 3.0?

I need to find out how far down the directory structure inside a working directory goes. If the layout is something like

Books\
Email\
Notes\
    Note 1.txt
    Note 2.txt
HW.docx

then it should return 1, because the deepest items are 1 level below. But if it looks like

Books\
Photos\
Hello.c

then it should return 0, because there is nothing deeper than the first level.

It's not as pretty, and arguably not as "Posh" as Keith's, but I suspect it might scale better.

$depth_ht = @{}
(cmd /c dir /ad /s) -replace '[^\\]','' |
 foreach {$depth_ht[$_]++}

 $max_depth = 
  $depth_ht.keys |
   sort length |
   select -last 1 |
   select -ExpandProperty length

 $root_depth =
  ($PWD -replace '[^\\]','').length

 ($max_depth -$root_depth)

Something like this should do the trick in V3:

Get-ChildItem . -Recurse -Name | Foreach {($_.ToCharArray() | 
    Where {$_ -eq '\'} | Measure).Count} | Measure -Maximum | Foreach Maximum
