Hi. Starting out by just saying that while we seem to have very irreconcilable views on how to scale steemit, I'm actually not a troll. Promise.

Your idea does seem very interesting, and I had some thoughts on it.

Firstly, have you considered publishing your token on Ethereum, instead of Counterparty? If you went this route, you could even have your token on real exchanges, such as Etherdelta. Fairly easy to do airdrop style currencies over a smart contract.
Granted, that you'd have to find a decent solidity dev to write your ERC20 token so that it could securely pay dividends, it would make it a bit more publicly available? Maybe?

About the name in the comments above, and just a nitpick here. I think Counterparty only allows 4 letters and longer assets. Only BTC and XCP being the exceptions. So you likely need another letter. SPTY, maybe?

And finally, (this is just ignorance on my part), do dividend distributions only take one TX fee on counterparty? (Since it is run over BTC). If it only takes one fee, that would work, but if it is one fee per token holder, likely most of the funds will end up spent on just moving the stuff.
(Actually curious how this works for a personal project too, so if anyone knows the answer to this last bit, I'd greatly appreciate it.)

Anyhow, just my 2 cents on the matter. It's an interesting idea, and I wish you luck. :)
