your question probalby best asked on the gnupg-users list itself:
But now that you are here, I'll have a go at it anyway.
Note that GnuPG is quite specific towards encrypting, verifying
single emails or files for asyncronous transfer.
If you have online access you could use scp or a networkfilesystem over
an encrypted VPN as well.

Check out http://www.gnupg.org/gph/en/manual.html#AEN210
for some of the concepts.

Short answer: You do want to use a hybrid method with something else
as asynmetric method. AES is only symmetric, but will be used inside.
