I like algo change idea. As for now it is mostly for ASICs mining.
So coin loses the ability to attract new users.

Algo must be something that perfectly work with GPU and CPU, to exclude mass botnet mining and ASIC mining.
And transfer must be quick and simple, cause Zerocoin implementation is more important now.

Cryptonight is nice, GPU and CPU hash speed is not vary greatly, But I think it will not be easy task.
May be it will be simplier to go to something like X11, Myriad or Groestl.
