By the way, they're called Safenet now (just in case you're trying to find them). They are pretty good, though we're using an older dongle. They're releasing a new dongle package that is supposed to be more physically robust. One thing to consider is that USB dongles can be easily pocketed. Try to make sure you have a method for locking it down or secure it somehow. On our other product we use a software security product. The one we chose has proven to be a mistake and we'll be fixing that soon. We're considering moving to a unified system for both of our products. Sentinel RMS seems to be an interesting solution, I think it supports both soft and hard licencing. Anyway, I think we pay about USD$26 for our current dongles, but we're buying about 2500 a year.
