Yes, and that's an important thing to undertand: every Counterparty action (issuing, buying assets, betting whatever) means a IXC transaction. Which means a IXC fee to miners. So the more Counterparty is used (for whatever purpose), the more interesting IXC becomes from the miners' point of view.

I'd like to give a reason why I think full Counterparty (with betting) might be a "killer app" for IXCoin (Johnny actually already linked to a testing implementation of this idea http://testnet.xbet.io/start ): it allows an easy set up for a sports betting exchange (ala Betfair). Anyone (the trusted party) can act as a result provider (the feed), say Vlad is covering NHL final games. Then everything else works in a trustless manner: people are offering/accepting odds (depneding on results offered by Vlad) and the protocol takes care of the rest (and Vlad takes his cut for the use of his service). And again: every single one of those actions means an IXC fee for our miners!

Also take a look how NXT Asset Exchange is doing! We could have the same with Counterparty (Vlad could start selling stocks for his "betfair service" ) but with the security provided by the IXC network!
