Another option would be to buy some Android tablets to use as remotes. I have several low-end Amazon Fire tablets ($30-50 each) that I use only for DCS. So far, they work well. I understand the frustration and the desire to avoid adding yet another platform, but that might be the simplest way to go.
Also, in an early post it was mentioned that the user didn't want to delete the app and reload it due to the cost of buying it again. As far as I know, once you have bought the app, you can download it again without an additional charge - I've done that with my Androids - although this may have changed with the recent reorganization at MTH.
I feel your pain.
