At the risk of being "flamed" some of the OBIEE visualizations seem less than state of the art.
Are there any alternatives you can use with OBIEE to push the envelope?
A couple of options; -

I'll leave others to the flaming, let he who has never thrown stones at the product work for Oracle...
Thanks - do you know if visualization desktop needs a separate license?
Also - do you know of any more useful materials on Jet - by useful I mean worked examples?
On all matters of licensing best to refer to your Oracle Account Manager.
Though - without prejudice - this blog would seem to say the licensing is covered if; - "free for customers who have visual cloud solutions or an on premise version such as VA"
