statically or using a shared library, the combination of the two is legally
speaking a combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the entire
combination fits its criteria of freedom. The Lesser General Public License
permits more lax criteria for linking other code with the library."

If you use oPortal, then everything that uses it must be released under GPL.
The alternatives are to issue oPortal under the LGPL or another less viral
license, or issue a specific license to Aral allowing him to do what he
wants -- perhaps in return for something.

I am not a licensing expert but I know we have some people on the project
who are pretty well up on this sort of thing. Guys, any comments ?

I believe I have a firm grasp of the GPL license as it pertains to software
itself, however in this case, if we were to use oPortal, could custom
portlets that we create have to be released under GPL? Would a site that
uses oPortal come under GPL?
