Its a hard marked, not easy to make money with a danish licens, my guess is many sites will close in the next 12 months an PokerStars / Danske Spil (Danske Spil use same software as Party Poker) will split the danish marked between them, maybe a few more will survive.
First poker room with danish licens are already in problems an will close tonight (http://www.redclubpoker.dk)
Here can you find list over danish sites with licens http://www.skat.dk/getFile.aspx?Id=92058
