In general I also like Hardware locks, and certainly would prefer it to the Algor Flexm Licence system, merely for portability in moving your licence to your home PC.
However, one can end up with multitudes of hardware locks. In the old days I had up to four parallel port locks in at the same time. I had to support them with a cardboard structure as they were sagging under their own weight, not to speak of the printer cable that still needed to be plugged into the end of it all. And then you start getting compatibility issues where the one lock does not like the presence of the other etc.
So I am not as hardware lock friendly as I was.
I would like a system whereby you can log off your licence via the internet, and then log back onto it from another location via the internet, so you just need two brief sessions of connectvity to move from one PC to another. Algor requires that the two PC's be connected to each other (via a LAN) which can be totally impractical (but is aimed at Notebook / PC transfers).
