New Bitcoin Security Standards, multi-signature wallets are becoming standard.

Bitalo.com explicitly mentioned: Multi-Signature combined with backup transaction technology. Thanks to Two-Factor Authentication you can setup your wallet even on a fully hacked computer and thanks to a backup-transaction you get your bitcoins out, even when the website is completely offline. This is the new standard I hope every Bitcoin site will adapt.

Problem with multisig transactions is that they are big - less of them fit into one block, so they essentially become more expensive.
I guess their price will eventually limit the usage. Not so much a lack of software.
