And you are posting this to accomplish... what?

Do you work for Longtail? Or are you just posting because you are genuinely concerned? The fact of the matter is that, yes, you are correct in that a commercial license is required for the 4.X code of JW player as outlined in the license that I (meaning me) have paid for. However, the JW player included with vShare is the 3.X player which was released before the commercial requirement existed and, thus, is exempt from licenses.

But, getting back my original statement, you are not going to accomplish anything by making a post like that, at least not here. Most of the people who use vShare probably do not care that licensing exists or is even required for 4.X players. A lot of the people who run vShare do not even use JW (most have moved to using commercial players). Almost no one here has ever modified the JW player in any way. If you really want to "fight the good fight," you should direct your post to asking the admin to choose a different player for future releases versus going after people here who may or may not know that licensing is required for the newer players.
