Here is a subject for discussion. What's your opinion on this?

There have been a handful of queries from people who wanted to use the Exiv2
library in their proprietery software. Most suggested changing the license to
LGPL, someone now appears serious about a commercial offer.

Technically and legally, it seems feasible to use a dual-licensing model for
Exiv2: a choice of GPL and a commercial license. (Real companies that are
doing this include MySQL and Trolltech (Qt).) Of course, I could only
re-license the code for which I own the Copyright, which includes most of the
library right now. Also, there is a precedence of some sort, the Vizrea
agreement (http://www.exiv2.org/whatsnew.html#5).

The main intention for Exiv2 is to contribute it to the open-source community
under the GPL. On the other hand, if it turns out that it could at the same
time pay for some of the time invested to develop and support it, why not?

However, the concern and question is whether this would deter people from
investing their time to contribute to Exiv2 or in some other way negatively
affect the open-source project? What do you think?
