Adding a Sonos Play:5 to a portal based internet access system

Hi Everyone,

My first post here! I have a bit of a weird question. I am planning to use my Play:5 at a party at a location where the internet access is provided through a portal , where every device that wants to connect gets redirected to a portal where the user has to type in a username and password in order to get connected to the internet (something like a public WiFi Hotspot, but then better download speeds :-) ).

I am wondering how to get the play:5 to connect at all, as there is no way as far as i know to interact with the play:5 in order to provide the username and password.

Thanks!

Yves
