Things that could expedite this:
Better affordable EDA tools (maybe even open source? startups that succeed and become self-sufficient would pay big bucks for customization and support). Especially for analog!
Some sort of business model which pays for masks, such as perhaps taking a percentage of the money in exchange for a MLM mask. This could be something that a mask work company does. Another related but orthogonal startup idea(albeit much harder than an app like snapchat)would be to develop a maskless lithography technique for cutting edge nodes, such as electron beam lithography.
