Not really.
<citation required> I would think there are a few uses of LOA in the telco/SP world, at least: 1) 'can I make this cross-connect happen?' 2) 'can I do some work on this link/path/fiber/conduit on behalf of <customerX> where the entity to be worked on is <providerY> infrastructure' 3) 'Please accept this internet number resource from <customerX> when the number resource is authorized for use by <entityA>' I would love to see ROA take over the 3rd of those, since it's a clear indicator that: "RIR authorizes LIR to use <number resource>, LIR authorizes AS-OWNER to originate <number resource>" and by 'clear indicator' I mean: "has some cryptographic/PKI backing you can follow to the RIR in an automated fashion" Where 'LOA' generally is a xerox of a photocopy of a fax of a dot-matrix printed MS-Word templated document which perhaps has an X on the 'signature' line... -chris
