I haven't researched the PDF -> PDF/A route yet. It's possible that
some information is lost in the PDF generation step making it harder
to translate from PDF -> PDF/A (a trivial example is a PDF in which a
non-standard font is used but not embedded).

It looks like Adobe Distiller (part of Acrobat) might be able to turn
PDF -> PDF/A (especially if you're doing all of this work on the same
system).
-- FOSS --
If your source document can be read by LibreOffice, use it to generate
PDF/As. That's the simplest FOSS tool I've used so far.
For those willing to roll their sleeves up a little bit, there's
always ghostscript on the command line.
If we take a look at ghostscript, we find this useful information
(http://ghostscript.com/doc/current/Ps2pdf.htm#PDFA).
"To create a PDF/A document, please follow instructions about creating
a PDF/X-3 document, with the following exceptions..."
So the docs at least say that it's possible.
For people who don't want to wrangle on the command-line, there is a
print driver. CUPS-PDF is designed to make it easier for people to
print to pdf on OSX
(http://hints.macworld.com/article.php?story=2007082812233971)
Apparently on OSX, CUPS-PDF uses ps2pdf. I don't have an OSX system
nearby for testing and tweaking, but with a little work, I assume that
one could massage the install process a little bit and make it
possible for a user to simply print to "Local PDF/A Printer" from an
application, and have a nicely compliant PDF/A pdf spit out the other
end.
