API max connection with the same consumer key

limits

#1

How many connections can do with the same consumer key? A single connection, some connection with distinct access token…

E.g.
I develop a desktop application which download some tweets for each client and do something useful with them.
I have the consumer key/secret of my application. Each client runs the application on his computer and uses his access token.

Does this situation allowed?


#2

Only one with a single consumer key. Attempts to do more are against the Developer Policy and Agreement2 (section II.B to be specific). For the benefit of all developers of our system, we have rate limits in place, and attempts to circumvent them may lead to app suspension.
