No solution at all from me, just a suggestion: save the document in rtf and see what happens in the exchange. A rather small test document would be advisable.
You can open an rtf-document with Notepad (shift-right click, Open with ... in Explorer), and then you'll see all the codes.
I don't even know if language settings are saved in the rtf-format (it might be defined single language only), but an experiment might be informative.
The only workaround I can see is that you define your own tags (like [ENG] and [/ENG]) and write some clever macro to select the text in between and set it to the correct language. Take care to write another macro to delete this tags when the document is finalized.
It's an interesting problem. Did you search google for it (try web and groups both)?

I have the International version of MS Office 2000, supporting a number of languages. When I write a multi-lingual document and use MS Word's Set Language menu command to identify the language of particular words (for the Spell- and Grammar-Checks) and I send that MS Word DOC to someone else's computer for modification of the English portion, they see DIFFERENT languages identified by Set Language on their pc, and I see yet FURTHER DIFFERENT language settings when that MS Word DOC is returned to my pc. We DO have MS Word's automatic language identification feature DISABLED within Set Language to prevent spurious identifications. Is there any way to EMBED the Set Languages settings for an MS Word DOC, similar to how you Save with TrueType fonts embedded, for MS Word DOC to be transferred from one computer to another?
