Localizing a plugin

[BillOatman 575]

I have a on screen message I will be sending from a plugin.  I would like it to be localized.  Searching tells me that plugins are more or less on their own for that which is fine, but how can I tell the current language of a particular client? If possible by sessionID.

Hi, we can probably look at making that information available on the session but it currently is not.

Thanks.  For now I'll assume server locale.
