I have been playing Portal 2 from the start in order to collect trading cards in the Steam trading card beta. I have collected four cards so far, and when I look at my badge process it gives an overview of the cards I have, and the cards I'm missing.
The bit that I am questioning though is that in the top right corner it states "No card drops remaining":
I have only collected the four cards today for Portal 2.
Does this mean that there is a per-day limit on the number of trading cards you can get per session? Is this a per day limit or a per gaming session limit? Is there even a limit at all?

As per the FAQ page:
In the instance that a game has an odd number of cards, for example Counter Strike: Global Offensive - which has a total of five cards - the number of cards that you can collect is rounded up. This means that you can get three out of the five cards.
The drop limit is permanent and it will not reset.
However, there now is an additional way of gaining cards:
These booster packs are randomly given out whenever a badge is crafted (as can be seen by the badge eligibility text below).
As for statistics, there is now also a "How do I earn card drops?" link on the badge progress:
This then shows an overlay with additional information (what earned you card drops, in particular):
