Multiple users sharing a .aspell.en.pws file

Hi,

 

I have a team of people that use aspell to spell check documents that want
to have centralized, shared, list of non-dictionary words.

 

Would it be possible for me to just link every user's personal
.aspell.en.pws file to another single file, such that when they Add a word
to the list it then becomes a valid word for all users?

 

Will aspell handle file-locking so that no collisions or damage occur to the
single shared file?

 

I'm thinking an alternative might be a cron job that grabs every users
personal .aspell.en.pws file, concatenates and de-dupes them, then use that
file as an -extra-dict?  But that doesn't seem as clean.

 

Or is there a better way for me to implement a shared word list?

 

Thanks and best regards,

Steve
