The problem is that there is like 100 Litecoin clones. If you want success you would have to modify the algo, so CPU miners have a chance in the first weeks, until a GPU miner comes out.
pure cpu mining is quite vulnerable to vps mining and botnets, im still waiting for the coin that uses gpu power along with cpu, im not a coder or anything so i have no clue if its possible, but it fights the unbalanced big mining rigs, be even more asic resistant (scrypt asics seem to be coming) and should be pretty crappy for vps/botnet mining. Your normally balanced cpu/gpu pcs will be the bulk of the miners and the coin would be well spread for a more stable market (you only cant stop the whale buyers/sellers i guess..)
