Does Foundry work as a support tool for the Ref in traditional sessions? Ref most likely has a laptop while others might be using mobile devices.
Our main problem is the burden of inventory management, maybe Foundry would help? It should support adding of custom weapons and items, though.
Oh yeah, for sure!
I basically use it just to show maps and tokens on my TV for the players, but it's SUPER good for inventory management.
You'll still have to add custom weapons and items, though. And I found it pretty easy finding good icons for everything by just googling "Item name" + clip art for images (and then turning white backgrounds to transparant layers to make them look better in-app)
Also, it automatically tracks ammo use if you do your attack rolls in-app.
EDIT: One neat trick for using it to display maps and such, is to connect to your own app through a browser as a player. Then it will only show what a player would see and not the hidden GM stuff
EDIT2: If you want, I could share my world (excluding 2+Gb of maps) with you... that should give you all the items and stuff you need and you can just delete the characters if you want.
