Thanks for asking.
All I can say is that -  yes - I'm developing a native Remote Buddy 
client and that it's my intention to make it available for free.
As with regards to the availability and it being available for free, I 
can only talk about my honest intentions, though, as anything else 
would be pure speculation.
Although I'm optimistic, I can't promise or guarantee anything as, at 
the end of the day, it's Apple, not me, who is to make the decision of 
accepting/rejecting the app into their AppStore.
Best regards, 
Felix Schwarz
