Long term contract, I just passed over a perm gig for $140k + benefits and options which would be close to the same in terms of total compensation. I mainly do very large JavaScript apps with Dojo and jQuery, I also do iPhone and Android development. Ruby and ROR are similar in compensation to those technologies.
kls's numbers are pretty normal compensation for these skills. The people saying it is numbers that are around half that are simply not in tune with market reality. The comments that $115 is too high are almost as bizarre as the comments that there are tech companies in 2011 incapable of dealing with remote workers, or realizing that that is what most successful companies are doing.
