[cc-licenses] CreativeCommons.org clarification on CC-BY section 4.a? (was Compatibility of Attribution license with Trialware)

  Terry raised a very good point and I would like to know if the folks at CreativeCommons.org can help us better understand CC-BY section 4.a.
  In my case I am making commercial screensavers and would like to use CC-BY 2.0 images. The trick is that the screensavers are to be distributed as trialware (like the original poster's game.)
  I understand that because the software would expire after a given period of time this might infringe on CC-BY section 4.a (the images are embedded in the binary.) So what if I also install those images in a separate folder on the user's PC. They would also be accessible at anytime.
  Would this by comply with the license?
  Best regards,

Yeah, it would be inconsistent with "CC-By" since the license permits 
access indefinitely,
whereas the trialware shuts down after a period of time (i.e. the 
control prevents access at a time when the license -- CC-By -- would 
still permit access, hence it's inconsistent with the license terms).

The reason why this wouldn't affect the original poster's problem is 
just that the content under the CC-By is separate from the program that 
displays them. So as long as the content remains accessible even after 
the trial has expired, the license on the content is not affected, IMHO.
