I agree with the goal of never again having to do a hard fork to change the limit, but am not sure if linear increases are appropriate for a system that could grow geometrically.

Could you support starting with a 2MB cap that then doubles every year?

I'd might be OK with a 5MB cap that doubles when the block reward halves, depending on how it effects TOR/DSL users.

Between 2MB and 5MB is a reasonable starting point, although the 2MB is too tight for very long. It doesn't even have to double every year, just every two years to match bandwidth improvement:

Summary: Users' bandwidth grows by 50% per year (10% less than Moore's Law for computer speed). The new law fits data from 1983 to 2014.

Nielsen's Law of Internet bandwidth states that:

a high-end user's connection speed grows by 50% per year
The dots in the diagram show the various speeds with which I have connected to the Net, from an early acoustic 300 bps modem in 1984 to an ISDN line when I first wrote this article (and updated to show the 120 Mbps upgrade I got in 2014). It is amazing how closely the empirical data fits the exponential growth curve for the 50% annualized growth stated by Nielsen's Law. (The y-axis has a logarithmic scale: thus, a straight line in the diagram represents exponential growth by a constant percentage every year).
