Hi Mike -
The intention of the Named User license is for just what you are suggesting, i.e. someone who wants to use NCrunch themselves (for work or home), without constraint on who you are working for or the type of work you are doing.
There are no restrictions on having the license set up on multiple computers, provided you are the only person that uses it. The vast majority of people that use NCrunch do so for professional purposes (and in the workplace), so to say that a Named User license couldn't be used in this situation would kind of defeat the point :)
Cheers,
Remco
