[Zope] internationalization and localization

[Samuele Giovanni Tonon]

hi,
i have installed Zope 2.7.1 and i would like to make a some pages
available in different languages using TAL statement.
On google i find that this is possible in Zope 3 using 
i18n namespaces, however i would like to use it in a stable
environment .
Do you know if a backport has been done for it ?
If no, what should i look for to have similar features ?

Many thanks to all
Samuele
