If you're blind and stupid enough to sync a read-only anonymously
accessed repository back to the master then you're so lost I don't even
want to think about it.  You must only sync it in the other direction --
i.e. update the read-only server _from_ the master!

Sorry, but if you want any security for commit access whatsoever then
you MUST assign unique individual system accounts to every authorised
user.  Accountability is one of the three primary components of
security.  You cannot have security without having accountability.  No
ifs ands or buts.  Period.  All you've got to decide is the level of
security you want and how to implement it, while at the smae time
keeping track of where computers and networks can turn tiny threats into
gigantic overbearing problems.

I don't think you are, to put it bluntly.  You've been spouting so many
misconceptions and falsities that I wouldn't trust you within 100 yards
of a root password for any system I cared about.

That's pure and simple BS.  Sourceforge uses only SSH and they have tens
of thousands of users, if not hundreds of thousands.  Certainly it scales.
