When doing mobile Web (browser) payments the connectivity issue wouldn't be relevant but when doing payments in a brick-and-mortar shop I see Internet connectivity as a stumbling block.  This IMO excludes server-wallets unless they do "intelligent caching" like the Google Wallet.

Anyway, I wouldn't design a mobile payment system so that it requires Internet connectivity.  Pushing [an encrypted locally signed transaction + a URL to the bank] through the merchant seems like a viable approach both for Web and Local payments.  Assuming that the merchant also is off-line is IMO bending things one step too much.
