Hubble Law and expanding universe

[Huej]

If the Universe were not expanding uniformly (i.e., at the same rate in all places), then would different places would see a different Hubble law than we do? And if If the extragalactic distance scale changed, would the Hubble constant change?

Fact is, that indeed there is some research that says this - see this article http://www.universetoday.com/19509/the-universe-is-not-expanding-uniformly/ from 2008, so parts of clusters of galaxies, move in different velocities than others and there are deviations from Hubble flow called "peculiar velocities".

Yes to both, though large deviations would require distance scales larger than anything we can observe.
