Hi wolterh,
Welcome to pokerth, glad you like it. And your post is a very eloquent (not to mention verbose

) one: I rarely have to look up words but I did not know the word ambit.
Regarding the poker chips, most of the sounds should be already there, although I do not use them myself so I don't really know how much they add to the experience at this time. For the graphics, I take it you are thinking of something like the partypoker UI (as far as I can tell by looking at the google image search results for
partypoker)? I am not quite certain how far the devs want to take the UI customizability - have you tried the 0.7 beta yet, by the way?
A ranking/points system and stats are in the official roadmap (check the Roadmap link on the website). The infrastructure for different servers and server types is already there for the most part: it's possible now for anybody to compile a server and host games.
I hope a ranking system will not get in the way of the relaxed nature of most of the games which you mentioned, personally I don't mind the flipside of this, which is the sometimes
very loose playing style of some players.
I have heard of the pokerth software already being used in more competitive environments though, if you google
pokerth esl you will see an example of this.
Again, welcome and have fun playing, maybe we'll meet on the server sometime.
