Esix 2-user license - is it reasonable?

[Andrew Herbert]

Would someone familiar with Esix rev. D please explain how the 2-user
version carries out its restriction.  I would hope that the basis for this
would be a limit (of two) on the number of different uids logged on to the
system at any one time - how does this compare with reality?

Any comments on the suitability of a 2-user version (rather than unlimited)
for a single-user workstation?  Also, have upgrades (in the past) been
more expensive for the unlimited-user version compared with the 2-user one?

Thanks,
Andrew
