Sorry, but some people don't care to read plain text with page after page of copyright and disclaimer info in front of it.

By now, many a lot text are available in HTML, too (and if someone submits an HTMLized text, it wil be accepted, of course). The spoiler plate issue will go away, once switching to XML is done.

Wikibooks plans to host many public domain texts; basically anything in the public domain you would expect to buy in a college bookstore or find in a university library.

Not a different intention; the PG heads for quite the same goal ;)

But our focus is on adding value to those texts by wikifying terms to point to Wikipedia articles and also adding annotation in the "margin" (a feature that is being worked on for Wikibooks).

This is of dubious value. Why don't you trust in the reader use wikipedia's search feature? Writing good annotations is a difficult job; annotations are mostly "gelehrter Wind" (G. E. Lessing). At least, make it possible to switch of the linking and annotation stuff (cf. the Perseus project).
