According to the info I got from Radnicki mountaineering club in Belgrade, you can't obtain the permit at Gusinje police station anymore this year. Apparently obtaining the permit via Albanian embassy is also very difficult (from what I've heard). Crossing the border at your own responsibility is possible, although you risk being caught by Montenegrin police. More details in my trip report soon.
Any more redtape news welcome!
There were no problems in obtaining a permission for Maja e Jezerces in October 2006. All you need is to visit Montenegrin police in Gusinje and in Vusanje - the police will ask you for your passport and planned route. Everything takes 5 minutes, if you don't want to stay for a coffee or a tee :-)
The border permits are not a problem. Getting them fast may cause some headache, but there are several companies who provide the service. I Climbed Jezerc with Balkan Natural Adventure
