I've just use'd the TeX hyphenation tables and the algorithm from
Tex re-implement in Erlang.

Yes - I'd like a PDF reader in Erlang - and I'd like to write GUIs
with the *same* layout language as used for creating PDF (like go 'ol

I want the layout language to be XML
The programming extension language to be Erlang
The fonts to be Postscript Type 1
The output to be PDF
I aim (of course) at better quality than TeX - whether I can do this
remains to be seen.
I have been reading books on Typography and there are a lot of neat
ideas around that seem never to have been implemented, like for example:
Hermann Zapfs optimization which is:
Add an extra blank at the start (end) of a line - kern against the
blank and throw away the extra blank - this is said to produce better
optical alignment of the margins.
Also do what Gutenberg did in the 42 line bible - move right hand
punctuation slightly into the margin - this is only node in PDFTeX as
far as I know (and with pleasing results)
I also want to bring some common sense typography into documents -
please don't set wide A4 columns in 11/11 TimesRoman :-)
