I'm only guessing Mykel since I have no firsthand knowledge but I'll attempt to shed some light at least until Stefan can respond.
On iphone the app itself is free, the player pays a small fee for individual upgrades such as the ability to change their look. Something similar to this could be transferred over to the client version. The client would be free but you might pay extra for benefits. It could be things like look, weapons, events, guilds, houses. An example of events would be a small fee for entering but the item won might be of a high value such as a stronger weapon not available to normal players.
As far as his second quote goes. I believe he's saying that they would like to use Graal as a development platform for new types of games vs just keeping every server as old skool Graal itself. Basically changing with the times. Much like they tried to do in a sense with Graal 3D.
Remember, I am only guessing myself here. Do NOT take what I say as the gospel truth cause I could be completely wrong
