What can i say , this is the absolutely best radiusserver on the market. Every penny is well spent. Of course i was very sceptic in the beginning because it was running under perl. But all i can say here is never underestimate perl. But once again perl shows its power. With Osc's products you will have a superb authenticsystem, with the freedom that comes with that is almost running on any flavour. And if you enter problems you will get the very best support from their supportteam, take their job very seriously. Dont spend lots of time and money finding a radiuserver that shall serve your needs, i can almost bet that OSC's radius (Radiator) already do it for you. I really recommend this product
