Opinion about a ActionsPane in VSTO

[Vivien Parlat]

Hello,

I have to create an action pane using VSTO. Its aim is to help the
user which enters some data. In fact I already made it.
But here is the point:
- the action pane has to be usable with existing .docx;
- the documents, once processed with this pane, must be readable with
Word 2000 (with the addin), this implies they cannot be attached to
the pane.
- the future user of the pane cannot have admin rights.

I'm considering following solutions:
- to embed an external docx dynamically from a master document
attached to my pane. But the master/detail documents look quite
experimental in Word, and I couldn't achieve the process.
- to open in the same time as the document, a file which contains a
macro which would attach and unattach the pane to the clean docx. Thus
the user could click, the pane appears, modify the docx, click, the
pane disappears, save. But I couldn't figure out how to do this.

Do you have any suggestion about this ? Admin rights would simplify
all of this, but I have no choice.

Thanks in advance for helping me (and sorry for by bad English)...
