[Ogf-l] OGL: Perpetual vs. Terminable At Will

[HUDarklord]

The OGL is supposed to be a perpetual term grant of rights concerning gaming materials.

Query to the legal eagles out there.  Are there some legal jurisdictions that treat perpetuities as contracts which are terminable at will (or are "indefinite in term")?

If "yes", were a person using the OGL in those jurisdictions, would the OGL be considered an "at will" contract rather than a "forever" contract?

I think the new Creative Commons licenses use the phrase "perpetual (for the duration of the copyright)".  Is this to get around those jurisdictions that might otherwise consider the term "perpetual" to be indefinite in term unless clarified with a specific termination date ("the duration of the copyright")?

Should the OGL be modified to include the phrase "perpetual (for the duration of the copyright)" or else "for the duration of the copyright on any material so licensed"?

Thanks,
