[c-nsp] Rancid & UDI (Unique Device Identifier) = inventory management?

[Thomas Kernen]

Is there anyone here that has been playing with Rancid and the UDI 
feature in some of the latest IOS releases. Unique Device Identifier 
Retrieval was introduced in 12.3(4)T, 12.0(27)S (S1 for the GSR) and 
12.2(25)S.

I was wondering if someone had already written a patch for Rancid to 
CVS/diff this extra information that can be displayed on the CLI via 
"show inventory". I've tested it on 7206VXRs NPE-G1s and NPE-300s 
running 12.2(25)S, Cat4500s running 12.2(25)EWA & Cat6500 running 
12.2(17d)SXB1. Depending on the hardware platform it has more or less 
information (fans, power supplies, backplanes, etc..).

If anyone is using this already for SNMP inventory management and/or via 
Rancid (with the appropriate patch) I'm interested in their feedback 
(accurate data, serial number tracking, "ghost" serial numbers, etc...)
