Thank you for the link to Genitum...I had noticed it before and thought that it looked very interesting and complete, but I was concerned that it was not postscript. I always feel a little leary of TrueType...

I have also found the following fonts for IPA:

Newton from Paratype
<http://www.paratype.com/welcome_e.htm>

And Le Monde journal IPA
<http://www.typofonderie.com/alphabets/view/lemondejournalipa>

Also, a thread here at typophile from Peter Bilak mentioned an IPA version of Federa; will that be available commercialy however? (I do hope so!)

i am jut making some further improvements on Fedra Serif IPA. The fonts will be commercially available, but there is no publishing date yet. drop me a mail if you woudl like to know more.

the package is suitable for use with LaTeX. if they are type1 fonts, there should be no problem using them with some other software:
