New videostream in medialessons

Hi

Until now we can use two external streams in our medialessons in Xerte. I am wondering if an other stream can added... It's about Mediasite, a huge platform for weblecturing in universities (and of course my college for vocational training).
Examples can be found here: [url=http://] deltion.mediamission.nl/Mediasite/Showcase [/url]

I spoke a manager: they are willing to give the proper information to work it out.
