Using invoke-command to run 'vssadmin list writers' on several servers, how do I sort the results from each server?

Question

Hi I am a PS virgin so be gentle with me. I am trying to run the vssadmin list writers command on 8 servers.
invoke-command -computername srv-bx-hvc1, srv-bx-hvc2, srv-bx-hvc3, srv-bx-hvc4,
srv-bx-hvc5,
srv-bx-hvc6,
srv-bx-hvc7, srv-bx-hvc8
-command {vssadmin list writers}
The command works but I cannot tell which response is from what server.
The objective whould be to eventually have the command so I know which server has  failed vss writers if possible restart them automatically.
Any thoughts on how to achieve this lofty ideal??
Thanks

This is a tweak to the example that JRV listed.  I am using this code to just pull the information about the Exchange Writers but you could adapt it for others.
$servers='sdcexmail001','sdcexmail002','sdcexmail003','sdcexmail004','sdcexmail005'
$servers | %{
$sb={
$writers=vssadmin list writers
New-Object PSObject -Property @{Server=$_;Writers=$writers}
$ServerName = $_
$out = invoke-command -computername $_ -scriptblock $sb -Argumentlist $_
$WritersData = $Out.Writers
for ($I = 0;$I -le $WritersData.Count -1;$I++)
$Data = $WritersData[$I]
If($Data.StartsWith('Writer name:'))
$WriterName = ($Data.Split(':')[1]).Trim()
$WriterID = ($WritersData[$I+1].Split(':')[1]).Trim()
$WriterInstID = ($WritersData[$I+2].Split(':')[1]).Trim()
$State = ($WritersData[$I+3].Split(':')[1]).Trim()
$LastError = ($WritersData[$I+4].Split(':')[1]).Trim()
$info = [Ordered]@{
'ComputerName' = "$ServerName";
'WriterName' = "$WriterName";
'WriterID' = "$WriterID";
'WriterInstID' = "$WriterInstID";
'State' = "$State";
'LastError' = "$LastError";
$object = New-Object -TypeName psobject -Property $info
$object | Where-Object {$_.WriterName -like '*Microsoft Exchange*'} | Select-Object -Property ComputerName,WriterName,State,LastError
