OK, here's an interesting one...
There is statistical evidenence (at this moment) that 30% [exact number] of HASP4 dongles have a different relation between their Secret Table and passwords, a relation not fully understood yet.
Besides, it is not clear yet, how can a dongle with an old version of Secret Table be told apart from one with a new version without retrieving the table (i.e. whether there's any sign of the version or how to know the version without the dongle on hand).
