The mobile license isn't really just for mobile export. It is for no limitations digital distribution of all 5 target platforms (windows, mac, linux, ios, & android). Also there is no limit for how much you can receive from crowdfunding. The only limitation is that you can not offer your game as a physical product in the pledge prizes or after the campaign. If you want to offer your game as a physical product then you need to purchase the pro license (per title) which has no limitations at all & no enforcements of any kind such as branding/watermark.
Sure the mobile license could probably be lowered to half current price or even €99 (per title) which I think would be acceptable. Having said that I'm not sure that Thomas or Alex will be willing to edit the current license plan any further. Besides we've already reduced both the commercial licenses by over €1k & removed the royalty tax. If we reduced it again, then people would assume we could reduce it further still... where would it end?

In regards to the monthly subscription for UDK - I hope we will be able to sort out a similar plan at a future date (cheaper than udk, obviously), as I believe it would be welcomed by people on low incomes, or kids/students that can't afford to spend x lump sum in one go.
