The Bronze and Silver licenses are for single machine use only. Gold and Platinum can be used on any number of machines. So to be properly licensed, you'd need two Bronze licenses for what you have in mind.

Quoting from the Simon License Agreement:

The Bronze License and Silver License do not allow the Dejal Software to exist on more than one computer at a time, and you may not make the Dejal Software available over a network where it could be used by multiple computers at the same time. You may make one copy of the Dejal Software in machine-readable form for backup purposes only; provided that the backup copy must include all copyright or other proprietary notices contained on the original. The Gold and Platinum Licenses may be used on any number of computers within one organization.
