Why not use latest bitcoin/namecoin/ixcoin client with modifications to i0coin sections.  Also, if we stop merged mining, maybe we could use latest bitcoin client.  Smoothie just wants to pump litecoin.  Unfortuantely that is how it is working in these alt-coins.  Let them fail on their own.  95% chance I have the 5000.  No exchange means no coin.  Maybe use PPcoin. solidcoin compressed the chain once. Maybe lengthen the block time. and adjust the frequency every block.  you would think empty blocks would be small.
