Hi again,
According to the research that I carried:
There are many solution but I didn't see any real implementation.
In fact I'm working on also and I am searching for the same information. I posted many times to get information about Mesochronous interconnect and I found only this IEEE papers.
Now, I'm looking for a very interresting book that study in depth these issues and solves problems of delays in interconnects and clock skew.
Try to find it
Skew-Tolerant Circuit Design
