[news.eclipse.platform.swt] Re: Plugins Evaluation key

["kent" <kent@xxxxxxxxxxxxxxxxx>]

i am sort of the mind that nothing is going to ever be unbreakable so just 
make it for the mostly honest people.

My key does not work with dates, but yours could. I just make a registry 
entry on intallation of the date, you can use the preferences api for this.

You are right if you change the date then it breaks, but you could get the 
date from a date server. There are other holes but I won't go too much into 
details.

The share-it key server works by royalties, they get something like 15% but 
for that they also take care of all the credit card stuff. So far I am happy 
with them.But you could set up a key server no problem, I just decided 
against it.
