I remember reading something about this (or something like it) last year
or so. Looks like the fonts are finally ready for market.

It's an Arabic font with no shaping, no initial/medial/final/isolated
forms, and even designed with LTR directionality in mind as a
possibility. I don't know about LTR possibility, and I'm not an
Arabic-reader myself, but *maybe* one could get used to it. Would be
easier if there were a free version available too...
I can see this used in advertising, etc. And if there were simplified
versions, they'd go well in environments that may not have the software
or space to handle full Arabic typesetting, like cell-phones or
something. Well, remains to be seen. And sheen.
