hi,
this sounds interesting, i'm building an altcoin myself and would like to implement the same function in the wallet.
if you check silkcoin or banksycoin you can see the proof that it is possible to implement an IRC channel into a wallet.
i will need a bit of time to figure out how they did it but as soon as i can confirm that i know exactly how to build it i could do that for you as well.
as for how to provide the option
"to earn a multiplier on their Proof of Stake interest if they have X amount of coins in their wallet."
i am not sure how to do it but could try to find out.
let me know what you think,
