Forum OpenACS Development: Status of OpenACS 4 globalization

I'm going to make bilingual site which will use iso-8859-2 and
iso-8859-5 charset encoding. Therefore multilingual support is a
necessary.

I'd like to know, what is status of implementation of globalization
support in OpenACS 4.
There is acs-lang package in OpenACS. But the package is not fully
ported and its implementation of globalization is far from
perfection. It seems, only TRN tags and locale-aware file reading
works.

I have to make some kind of multilingual support but I wouldn't like
to duplicate somebody's work.
So, Is there anybody, who is engaged upon further implementation of
OpenACS globalization?
