This would bee the Cherry on top .
I've been doing some research on this (specifically for Clementine support)
and it seems that MPRIS compliant players can pass the album art as
the "arturl:" return parameter of the .GetMetadata method (MPRIS1) or as
the return parameter "mpris:artUrl:" of the Metadata property (MPRIS2) as
explained here http://code.google.com/p/clementine-player/wiki/MPRIS
That should make the support for album art passing straighforward for MPRIS
compliant music players.
