[Spice-devel] Spice for commercial use

[David Jaša]

You've reached pretty ideal conditions for video streaming performance:
not bad bandwidth, Windows VM with standalone player (where qxl manages
to capture stream of original size) and you've got pretty good client in
terms of CPU.

If you do the same with linux guest, HTML5 video, low b/w network, and
underpowered thin client, the results will be way different. This is
what Yonit's series of patches will address.
