2016-01-14 22:55 AEST by Arthur Barrett - A client may be blocked form accessing port 2401 and 22 (SSH) by a corporate firewall, making it 
impossible to 'checkout' a repository.

The tool 'cvsgrab' creates a 'standard' cvs sandbox but uses viewvc/cvsweb/viewcvs to 'download' 
the files via HTTP:
http://cvsgrab.sourceforge.net

Such a feature may be useful for the client.  the '$CVSROOT' would need to still be pserver or ssh or 
whatever, but there would be a 'fallback', if that port is blocked to try port 80.

2016-01-14 22:56 AEST by Arthur Barrett - A further enhancement of this would be to use it to extend the 'sync' protocol or the 'rsync' feature to 
connect via HTTP - but that would create a large strain on the server:
