By the way, I just noticed that greenaddress.it is creating seeds that have 24 words instead of 12. Does anyone know what's up with that? They claim to be using BIP32 wallets so I wanted to see if they were using the default structure and if so, whether bitcoinj was compatible with it (before I switch to the one discussed here). But it seems we fall at the first hurdle ...
