From what EREL has shown us of what B4Android will be on first release, the Syntax itself will be similar, but NOT equal to what B4PPC uses, so there will be some syntax adjustments needed when converting from B4PPC to B4Android...
Maybe that can be one of the first projects if anyone is up to the chalange...
Regarding DLL dependent apps, that will be a bit more tricky, I supose, as there will be the need to create B4Android specific DLLs...
But then again, I could be DEAD WRONG!!!
