I suspect so. After all, it is just seen as a disk as far as md is concerned and it will do the same normal thing if you unplugged a single disk from the array.
But the latency over the net is much higher. Who knows if the kernel can handle this in all situations?
I'm sure the kernel can handle the slowness, it's the cache consistency one has to be careful with in these setups. With so many caching devices in the chain, one must make sure the write and read cache is consistent throughout.
