Mostly we used the glass playground, which you have access to if you have a pair of glasses. The playground doesn't perfectly represent the glass experience.. I say this mostly in regards to stylistic stuff (I.e. CSS rendering). You can have access to the API keys if only one dev has glass, if they include you in their dev 'team' . This grants you access to the playground. I'll be writing stuff up about it soon, to more explicitly explain the whole procedure, since the documentation (while sufficient) is rather confusingly organized...
