That's an interesting question. I would start by noting that “cross-subsidization” to me would mean implementing some of the proposals along the lines of iPod taxes, device taxes, and Internet taxes, which are cross-subsidizations and are, I think, a problem.
What I took the government to be doing in that case, including with the money that I mentioned is going to Creative Commons licensing, was to say that journalism is a priority and that it will take money out of general revenues to find mechanisms to adequately support it.
I would say that the same applies in this context. If the committee concludes that the marketplace currently doesn't provide enough revenues going back to artists, there are mechanisms to consider in order to say that we want to put money back in.
Some of the suggestions I tried to make off the top, including such things as funding open educational resources that pay creators up front and that give education flexibility in usage, are actually very similar to what the government has announced over the past year with respect to journalism. Similarly, providing support to ensure that Canadian publishers can make their works available through digital licensing would be another mechanism to provide funding into the system that ultimately helps support the market.
