I ran into this myself, It's quite easy to remedy the equipment profile. simply create a recipe using your equipment profile, then save that recipe to the could. from the computer without the equipment profile, open the recipe. then click the save equipment profile button. boom! saved to the new computer!
as far as inventory, It's not a whole lot harder but a bit. What i did was created a recipe using all of my ingredients on hand. when you select "add fermentables" or whatever, it'll give you the option to only select ingredients on hand. select all your ingredients, modify the quantities to what you have on hand. then export that recipe. when you open the recipe on the other computer, you can then make a shopping cart with the ingredients on the recipe, then add to inventory.
It would be super nice if the cloud would update your on hand ingredients, especially to the mobile platform because i would love to check if i have stuff when out shopping, but it doesnt seem to do that currently.
