I've been using it for about two days. I've been using Visor since 10.4 and was pretty excited to stumble upon this while setting up a new MBP and installing all of my staple apps.<p>Would I pay for it?  I might donate and often do to FOSS projects I get a lot out of (my machines make my money, so it's worth it), but given the amount of open source you've got in this plugin (Visor code and now Chromium), I'd probably just pirate it if you started trying to force me to give you money, out of pure spite.  I'm not entirely sure that you could even get around the licensing issues from the other code you're using (but maybe you can; I don't know).
