I would be more concerned about the "viral" nature of the GPL (I assume this applies to AGPL as well) i.e I would be happy to use AGPL code in my application and release any modifications I make (or create AGPL code and have others do the same for me) but there are parts of my applications that I really wouldn't want to have to release (because they are very industry specific and would be useful to competitors without modification and not useful at all to the general populance).
A similar license but one based on LGPL would be preferable.
