One question: is HDL sufficiently powerful to serve as a delivery
medium for mathematical and technical documents written in TeX?

In the current situation, such documents are typically served over
the Web as (1) PostScript [converted from DVI], (2) Hyper-TeX [really
hyper-DVI; requires modified DVI previewers], and/or (3) TeX source
[a big hassle!]. In the future, option (1) could migrate to Acrobat
documents, converted from Hyper-DVI to include hyperlinks.

Because TeX has dramatically raised the standards of typography for
technical manuscripts, any successful alternative delivery system
must have the ability to approach the same level of quality. I would
be curious whether you see HDL playing a role there.
