I don't know if it's completely transferrable to "G c", since I've never
used that, but I use unison to sync which messages are read and which
groups are subscribed to (I have .emacs and friends in git instead,
since I prefer version history there). I guess my setup would sync "G c"
settings too if they are in newsrc.

my ~/.unison/default.prf:
path=.newsrc
path=.newsrc.eld
path=.Mail
path=.News
ignore=Name temp.*
ignore=Name .*~
ignore=Name *.tmp

my ~/.emacs:
(setq gnus-directory "~/.News")
(setq message-directory "~/.Mail/")

I also run (shell-command "unison --args") in
`gnus-after-exiting-gnus-hook'.

If you're planning on being subscribed to the same groups on both
machines, why not take a backup and just try it out?

For me it has worked fairly well. I'm probably syncing some stuff I
shouldn't be syncing (I still don't really know what goes into
~/.newsrc{,.eld}), but I think the most serious problems I've had so far
is occasionally having to mark things as read that I'm sure I already
marked as read on the other computer.
