I'm not that worried about the complexity, so far it seems to be quite fast (although it's always hard to pin down the complexity of a numerical method exactly). And assuming that with n you mean the number of pixels I seriously doubt it would be n^2. But I'll definitely verify that. What I am a bit worried about is the non-locality of diffusion curves though. This ties in to the comment above about whether to make it a paint server or an effect, as that would be one way to at least constrain the output a bit. But even then you can't really render different parts of the fill independently. This could probably be mitigated by either again going back to something like a multigrid method or by changing the algorithm to play nice with tiling.
