As I see many authors strugling to get software license I think that I should mention a few things which might interest independant publisher.
There is an open source (i.e. free) software of quality for desk-top publishing:
Scribus
http://www.scribus.net/
and a small presentation of it:

You can do nice PDF with it (you can even include those little javascript code that only Adobe Acrobat Reader can read).
It works on a Linux (and *nix like) OS, requires Qt (and KDE if you want the drag and drop function).
If you have a monster computer you might be able to run it on windows XP with cygwin.
P.S. there is also OpenOffice.org for those who can't afford the WindowsOffice solution. This one has a windows version.
It can import basic WindowsOffice files and the 1.1 release include a nice PDF export feature, which might be all you need.
P.P.S It might be interesting to include the different software usable for PDF publisher in the FAQ, with cost and comments from users.
edit: OpenOffice.org isn't only for those who can't afford WindowsOffice, its quality is on par with Microsoft software. Though familiarity, and formation cost are a huge restraint to change in desktop envronment. I can't comment on the quality of Scribus compared to Adobe software or QuarkXpress
