IOS – Since yesterday I can’t login to iOS developer forum. What’s going on

Take a look at the iOS Developer Enterprise Program FAQ. The key points are:

• No ability to distribute apps on the App Store.
• Only allows you to distribute your apps to employees or members of your organization through Ad Hoc distribution.
• The program is for companies/organizations to develop and distribute proprietary in-house apps to their employees.
• If you want to develop for other company than yours, that other company should enroll in the program and add you to their development team.

Yes. Although I couldn't find any specifics regarding the possibility of a Company having two or more iOS Developer Program accounts, in the Enterprise Program FAQ it is stated that:

If I am enrolled in the iOS Developer Enterprise Program, can I distribute my apps on the App Store?

No. The ability to distribute apps on the App Store is only available to developers enrolled in the standard iOS Developer Program. The iOS Developer Enterprise Program only allows you to distribute your apps to employees or members of your organization through Ad Hoc distribution.

If your company is enrolled in the iOS Developer Enterprise Program but would also like to distribute your app(s) to customers on the App Store, you will need to enroll in the iOS Developer Program.

Which means that Apple has no problem with a Company having more than an account, which is confirmed (with a regular program too) by my personal experience.

Even more, in the specific case you present, as each developer would need to use his personal legal name, it would be, on practical purposes, as if you had hired a developer who was already enrolled into the program.
