Remember that IXCoin is just one out of a whole family of merged mined coins, all mined together.
IXCoin and I0Coin help us see what no more mining rewards is like (I0Coin also giving us 1.5 minute blocks instead of the more common 10 minutes per block used by many other familiar coins), GRouPcoin and CoiLedCoin show us what forever mining the same number of coins per block is like, and DeVCoin has the same number minted per block forever while also giving 90% of the coins toward free open source development.
Notice that all of these coins are all free open source, and development of all of them goes together, just like when I0Coin solved the RAM problem and all the other coins then were able to make use of the solution.
So with all these development-needed ideas, you-all should be involved with DeVCoin as well as the rest of the merged mined family.
They all go together, and the funding-of-development department is DeVCoin.
Development proposals should probably be couched in terms of projects that benefit all the merged mined SHA256 coins, and bounties applied for from DeVCoin.
Let us not forget too of course the other members of the family, NaMeCoin which provides domains and aliases and such (usable by various things such as Open Transactions); GeistGeld (XGG) which shows us the bleeding edge of how fast blocks can be, and is so darn fast it might even need slowing down, unless maybe we are just waiting for hardware to catch up or something; and the new member of the family, UNObtanium, which gives us the rare-coin member of the family.
(Keep an eye on HuNTercoin too of course, in case they ever manage to get their merged mining working...)
