How do I share an entire bookmarks folder between two firefox sync users?

I am trying to share a folder of bookmarks I use at work in firefox, so that this specific folder is available at home.

I am using Firefox Sync to synchronise among diferent instances of firefox in different computers and I am also using XMarks to share those bookmarks with Chrome.

This is the setup:

• Work computer: Firefox with [email protected] profile both in firefox sync and xamrks. Folder Work@company is to be shared.
• Home computer: Firefox with [email protected] where the Work@company folder is meant to be shared

Xmarks only allows sharing of folders as webpages and Firefox Sync seems to be all or nothing from the options I have seen and tried.

Has anyone figured out a way to share a bookmark folder with another computer?
