Sure, sorry, by web wallet I meant a blockchain.info/CoPay type setup where
the client has the private keys and signs txns, but otherwise relies on the
server for learning about the wallet contents. I tend to call wallets where
the server has the private key BitBanks but I don't know if anyone else
uses this terminology. It might just be a personal quirk of my own ;)

Fair enough. Yes, push notifications to mobiles in a decentralised way is
rather a hard problem.

I think what Gregory suggested is then the best approach for you to do what
you want. Whether it's worth the additional complexity is something I don't
have any feedback on, only you can judge that.
