No deception whatever.

The above converts the actual scalable outline font file itself.  The FMP, 
of course, *also* has AFMtoPFM to make the needed metrics file for 
Windows and AFMtoSCR to make the needed `screen font' files for the Mac. 
If you don't have AFM files, there is also PFAtoAFM, PFMtoAFM which 
together produce an AFM file complete with kerning pairs.  Maybe you 
should look at http://www.YandY.com/products.htm#otherprods

It is well known that MacroMedia does not understand non-text fonts.
Also, you may very well mess up the hinting if you read the font into 
FOG and spit it out in a different format (I say `may' because in the
past this was guaranteed to mess up the hinting, but I have not tried
the latest version).

For price information see the web page.  
If you want copies of a review, send  them email.

It does not.  The best information is in the out-of-print manual that
came with the Apple LaserWriter.  Next best information is from
Adobe in a Technical Report on `supporting downloadable printer
fonts' available in PDF format from their web site.

The FMP does.

It *is* a swamp. Some ambiguities. 
And the above mentioned references are complete with errors.
And, just to irritate R&R: ResEdit is not useful when it comes to 
Macintosh Screen font suitcases :-)

Why would that be a good test?  Why not try it first on some fonts from
Adobe first?
That way you don't have to deal with possible quirks of those particular
font files.
In any case, if you are serious about font conversion, why not ask on
where someone might actually know something about this sort of thing :-)
