Seeing as the Dogecoin community is so active on Reddit, this could be an interesting use case for Dogeparty.
Dogeparty is an crypto-token (e.g. securities) application layer built on top of the Dogecoin blockchain. Now that Dogecoin is merged with Litecoin's asic hashrate, the network is pretty secure against attack.
There are other options built on top of Bitcoin (such as Mastercoin, Colored Coins & Counterparty), but certain Bitcoiners have been worried about blockchain bloat, so Dogeparty could be a decent shout on top of another secure blockchain. Other options exist on new blockchains, but I think these are too unproven this point.

Web wallet: https://wallet.dogeparty.io (note: I do not endorse this, it's beta and as with anything in cryptocurrency be careful!)
