I've a dream (which will probably remain such, given the lack of free
time) of writing a D-Bus replacement, where the bus daemon only manages
clients registrations and interests (match rules), while messages among
clients are directly delivered, bypassing the daemon. You can read more
at http://blog.mardy.it/2011/01/concepting-new-ipc-system.html (just to
get the big picture, details need to be verified).
More concretely, I don't have any project of my own which could benefit
from this. If I find time and motivation, I will try contributing
patches to existing projects to use speculo, where it makes sense
(things like Telepathy contacts' presence status would IMHO be better
shared in a speculo area, but I don't see many chances of this happening).
If you are aware of some project which makes a suboptimal usage of
D-Bus, and where D-Bus is just an implementation detail, please let me
