The scope of any local utility (and that includes translation domains) 
is the site that it was registered for. It's therefore not surprising 
that a translation domain you added and registered in MYSITE are not 
available outside that folder.

Why aren't you going for global translation domains that are maintained 
as gettext PO files on the filesystem and registered using ZCML? My book 
(also the 1st edition) explains how to do that.
