Limit Downloads per timeframe - weekly, monthly etc.

Yes, but within 1 subscription.

Subscription for 1 week and 10 downloads.

Subscription for one month and 50 downloads.

So you mean scenario like this.

Subscription is one year with not more than 10 downloads a week.

Right?

I am afraid it is not possible. :)

I mean it is possible to implement but not possible to configure Emerald to work like this right now.

In the Emerald 9 we plan to add step distribution. May be this also :) But that are long plans not very soon.

Or may be you mean Cobalt paytodownload field? Then it is possible to control it in the field.

Since E9 beta is around the corner, any improvements in timeframes and limits?

( Sorry, almost no free time to have a look in the first pre-release :S )

Scheduled.
