Some sort of online client would be nice as far as not everybody can run the game. Like you can play online within web browser for 3% fee from your mined Motocoins.
And I would appriciate an Android app. Someone should make a bounty for that.
I think the best way to do a pool would be to have a program analyzes a bunch of maps very quickly and find the easiest one for that block. That map would then be fed to the workers. Each worker would try to finish the map. The first one to solve it would get a block finder bonus while the rest is split between everyone trying to finish the map on that block. The problem is how do you tell someone is actually doing the work and doesn't just have a macro going to make it look like he is actually playing therefore cheating the system. Ofcouse you could combat this by implementing something like no pay if you don't reach mid way down the level before the next block. Just spitballing.
