If OA's current protocol is 71, You can set the cvar "protocol" to "72" and
"oldprotocol" to 71. It will work fine with STANDALONE oa then. In either case,
negotiation of which protocol to use happens transparently from the user.

No. I do not intend to support any other legacy protocol than idq3's original
protocol. What will be supported are protocol 68 demos and the most current
protocol used by ioq3.
