Sharing data between Tcl packages implemented in C

I have 2 seperate Tcl packages, both implemented in C and compiled to
seperate shared object files. I want them to be able to share some
persistent data - a linked list. Unfortunately, one of the packages is also
compiled into standalone C programs, and as such I cannot presume access to
the other package, or to any Tcl commands. I would like the data to be
accessible if either one, or both of, the packages are loaded.

Can I do this without compiling into one shared object file?
