I believe the cost is not part of the policy.

Sorry I wasn't clear, how about these;

- If we make a distinction between Internet connected and non-connected, 
them having an assignment from one or the other can't affect your 
ability to get the other type of space.

- If I have an Internet connected assignment, that should not disqualify 
me from getting a non-connected assignment and visa-versa.

- If I meet the requirements for both, I should be able to get both. I 
would still have to properly meet the requirements independently for 
each assignment, but I should be able to get both.
