alea,
Thought I would drop a line to you showing how the MNO's are playing nice with Google's Wallet. Don't know what broke the ice but it shows to me the various business models should be interoperable.
As soon as MicroSoft confirmed there will be discrete TPM's and firmware based TPM's running in TrustZone for mobile devices, I stopped caring about the Secure Elements involved in mobile financial services. IF Wave announces they are using the secure element for something it will get my attention again.
Your recent posts on Ihub have been some of your best work regarding Wave. IMO.
