John,
I can't seem to find a device with the Cisco License info in it but I can use the ifTable as an example. When I use CLI to show the value of ifDescr attribute id 0x100c5 from the device, I see the following:
./show attributes attr=0x100c5 mh=0x40006d
Id Name Iid Value
0x100c5 ifDescr 1 Ethernet0
0x100c5 ifDescr 2 Serial0
0x100c5 ifDescr 3 Serial1
0x100c5 ifDescr 4 Null0
So you should be able to do the same thing with the attributes in the license table. This could be scripted to cycle through the models that support the license table, pump the output to a delimited file and bring it up in a spreadsheet.
