TeXnically, given that Type1 versions of fonts are available,
one _can_ produce correct PostScript (via dvips) or PDF (via pdfTeX)
files. PDF created by Distiller from PostScript with embedded
Type1 fonts does work smoothly.

Possibility to set correct CMAP resource (ToUnicode)
has been added to pdfTeX only recently. I've tested it
on a small example (creating PDF with characters out of
AdobeStandardEncoding, cut & paste under Win platform worked).
There is not much macro support is available, though,
and documentation is sparse. 

The way how to proceed? Maybe changing the default setup
so that Type1 fonts are prefered over bitmaps
in main TeX distributions (TeXlive etc.), 
and support of macro and pdftex developers by Adobe.
Writing white paper would be good starter as well.

Yes, sure. Glad to hear that Adobe is starting to take care of TeX users
(when TV Raman left Adobe, no support for pdftex development
at Adobe was available).

I am CCing to pdftex list (users of pdfTeX, version of TeX directly
generating PDF), and texlive list (development of most widespread
free tex distribution), too.
