Let $M$ and $N$ be n-dimensional open manifolds. If we embed $N$ into $M$, does there exist a fibration (in the sense of Hurewicz) over $Diff(M) \rightarrow Emb(N,M)$? I am aware of the results of Palais and lately Goodwillie in the case of compact manifolds, but I have no idea about the noncompact case.
