Our server, currently offering anoncvs and cvsup access, has room
enough for some extra load. Although the number of anoncvs users is
slowly but steadily growing, it's still fairly lightly loaded. So,
adding rsync access would not be a real problem I think. We could
always limit the amount of users to an acceptable level if it runs out
I haven't set it up due to lack of time and unfamiliarity with rsync and
because I wasn't sure whether it offered any real added value next to the
anoncvs and cvsup access we're already offering (I guess it does now). In
other words, we may support rsync access in the future but sofar it's
relatively low on my ToDo list. If it's high on yours, you could
give me a hand to speed things up. I could give you an account on our
server, and set it up in little time. If you'd like that, just send me
a private email about it.
