I have created a sourceforge project for the new Guile version of packedobjects:

http://packedobjects.sourceforge.net/

This is an early version without documentation. The API has changed from the Chicken version so I will document this soon. Eventually I will push back the improvements to the Chicken version.

So far it builds as a Guile module. I also need to look at how to embed this version into a C application.
