If you have Powershell (www.microsoft.com/powershell), the VI Toolkit for Windows (www.vmware.com/go/powershell) and the Update Manager PowerShell library (you get prompted to install it when you install the Update Manager client if it finds the VI Toolkit during installation) then a little script might work. This will prompt to connect to your VirtualCenter server, find all the ESX hosts, spin through each of the Update Manager baselines applied and then spit out a report of what is installed, not installed, unknown and not applicable. Its not pretty but gives you the framework and the rest is just putting a little "lipstick on the pig" to make it pretty.

foreach($vmhost in (get-vmhost)) {
foreach($baseline in get-compliance -Entity $vmhost) {
"`n`n----
"
$baseline.Entity.Name + " - " + $baseline.Baseline.Name
"----
"
"`n*** Compliant Updates ***`n"
$baseline.CompliantUpdates
"`n*** Not Compliant Updates ***`n"
$baseline.NotCompliantUpdates
"`n*** Unknown Updates ***`n"
$baseline.UnknownUpdates
"`n*** Not Applicable Updates ***`n"
$baseline.NotApplicableUpdates
}
}
