[Spice-devel] Question about Spice with Wayland

[Yury Shvedov]

Hi, Fabio!

Thank you for your interest to this project! But unfortunately this 
project now is in proof-of-concept state and usable only via loopback 
network. And as you notice it did not evolve by me for years. The 
problem is I changed my scientific theme by accident at this point and 
could not continue it as I have wanted. But I feel this project has big 
potential and space of improvement. It would be great if you want and 
can to handle this project and I will support you as I could.

Sorry for my english too! =)

Kind regards
Yury Shvedov
