I refuse to use Roll20 on principal I backed the KS, they promised Roll20 backer access for life, only to get shit on when they went to market. that translated into Beta access, a code for 3 free months when they went 1.0, and you get some gay flair for you account tagging you as a sucker. I didn't expect external access to 3 TB of storage and all the cool graphical whistles, but I was expecting at least Free but No Ads or maybe some extra asset storage. Plus their market place shits up the GIS results when I go hunting for assets.
Given it'd be OSR/OSE, There wouldn't really be a need for a VTT. Just something for handout graphics & white board.
Which is great because I am not giving any internet randos my IP for Maptool, let along people from this board.*
*they have some proxy options I have been too lazy to explore.
