[Zope] numeric formatting

[David H]

Hi List,

I will have to format numbers based on country and currency types.

I understand the locale module can do this.  I've done some googling on 
this but cant seem to get anything definitive.  I've read that the local 
module is not thread-safe but I do not know how this would impact my 
Zope app.  I do know that I would want to be able to change from one 
currency format to another depending on which currency conversation the 
user may want.

Really my question is, what approach is recommended for a Zope 
application to format numbers according to currency type?
