@Erel : we are discussing B4i and the requirements again on the chat.
What about having a virtual mac (server) running in your cloud where a hosted compile user can connect to remote desktop like?
Just allow safari to run so that we can download our app and upload it to the app store?
If it works like windows you could give hundreds of users access to just 1 virtual mac
as the load is minimal and concurrent users will be low too.
Not sure if mac (server) allows something like that.
