DLNA connetion to Kodi on Rpi3

Dear volumio community,

maybe it’s very stupid idea, but I have a Rpi 3 with kodi running as media-center remote controlling it with XMBC from an iPad - so far so normal…

…know I am thinking if I could stream form this media Center to another Rpi3 (+ AMp) in a wireless Speaker via DLNA?! I guess it will not connect just wit Upnp?

Until this Project I was only building Speakers on the hard ware side - you see I do Need some help on the Software.

I appreciate any answer!
