License use in the free world

When an Engineer, like me has to travel across continents,will I face difficulties using my transferred license via email orautomatically? What if have another but same release software dvdand I have an official activation code, will I be able and free touse, or will I, as many software companies, have unseen and hiddenstrings around the necks and choke me?
I am asking in advance because the last time I had to deal withSolidworks about an international situation it was.. well it wasugly!

Best Regards, in appreciation of input, thoughts, experiences andadvise.
