I've been out of the loop on all things TeX for a while now (demands of my
profession and other matters). I have a couple of general questions:
1. What exactly is the aim and purpose of XeTeX?
2. Since its apparently based on eTeX, and since bidi seems to be of
interest, why not integrate it with the Aleph project, also eTeX-based
(with an eye towards ConTeXt), and which already has the bidi stuff
implemented rather well?

If the idea is a kind of BiDi-Light (just paragraph and text), then
implementing a subset of Aleph's functionality (such as \pardir and
textdir) seems like a good way to go.

which is where we will need Aleph and Bidi-Full

Please also cc the Aleph list (and forward this thread) because others
there may find your project interesting or useful. If things get off-topic
ConTeXt-wise then the Aleph list would be a good place to continue.
Is Giuseppe aware of all of this (I assume he's on dev-context)?
