According to the wiki page the feature is in concept phase without any
design details so feel free to propose a design

That's what the proposed feature is about but nobody has even shown a
viable detailed design of the guest, client, and server (if any)
components. The server would be responsible only for opening a new
channel. The heavy lifting would happen on client side and the guest
side has to merely agree on features with client. However, to support
applications not specifically designed for spice you will probably want
a media 'decoder' driver in the guest that sends the data over to the
client instead of decoding in the guest.

Thanks
