Yes, indeed.  I think you can also use the fingerprint, or something else
you provide with the -r option to GnuPG.

They must be linked to the compiled library, not to the installed library,
so they need the LD_LIBRARY_PATH environment set up.  They also have some
other setup (GNUPGHOME and srcdir variables set).

Exactly, that's what the test scripts do for you :)  Try to run the tests
with "make check".  The complete way to run them manually is with something
like that:

$ pwd
~/gpgme/build/tests/gpg
$ GNUPGHOME=. srcdir=../../../tests/gpg LD_LIBRARY_PATH=../../gpgme/.libs .libs/lt-t-encrypt
 
for example (from the top of my head).

No.  Setting GNUPGHOME is basically the right strategy, because an
application should not be concerned about the configuration of the crypto
backend.

There is a mailing list that informs you about all changes in the CVS
version.  I have problems accessing the gnupg.org web site right now so I
can not dig out what the mailing list was and how you subscribe to, it
should be something like gpgme-commit or so.  Important announcements
are also sent to this list here, but regular development is just documented
in the ChangeLog and NEWS file.  

Thanks,
Marcus
