1) The application has little flexibility as to how it
    handles the color. Either it's stuck with sRGB, or
    double color correction is applied.

2) The gamut is limited to sRGB (or some other chosen
    colorspace), rather than the full gamut of the monitor
    being available to the application. This can be
    significant in proofing situations, particularly if
    optimized proofing device links are being employed.

I'm wondering, does the plug-in support separate color transformations for each 
window (including no-op transformations for those windows which should be 
color-managed by the application)? Then the applications could still do their 
own color management in their windows, or delegate the working space to monitor 
transformation to the compiz plug-in (by assigining the working space to the 
particular window as source color space for the compiz transformation).

I put in my reply from yesterday (I am replying to digest):

Applications, which want to do early colour binding and doing fancy stuff
with device links, thats possible through putting a hole in the colour
corrected desktop in their own window. They are free do whatever they like
with the full gamut available. This is as well a useful path for monitor

CompIcc is multi monitor aware as stated:
The Compiz ICC colour server, or short compicc, lets you colour manage your whole desktop at once and in hardware. Play movies, watch images on wide or narrow gamut displays. Each connected monitor is colour corrected for its own.
