discuss: Duemetri Public License (DPL) Version 1.0

[Mike Wattier]

Hi,

Excuse me if this is a silly question..

The pain you speak of, is this from a purely "legal" stand point?
If so, in what manner does it hinder or "cause pain" to an end user? 

The reason I ask is I am thinking of implementing something similar to this in 
my soon to be released framework in the hopes that it will provide a higher 
level of quality for the end users. As most programmers know, moduler 
applications can become diluted over time with third party "plug-ins/addons", 
some to the point where Module "A" by company x can not be used with Module 
"B" by company z, and it's the end user who gets screwed.

I am not a lawyer, just a guy who writes a ton of code so please excuse my 
ignorance on this point.

Thanks to all who contribute to the legal/license stuff, guys like me would be 
lost without you :)

Have a great day!
Mike Wattier
