I'm not volunteering for this - I don't have the time - but I just 
realized that I *do* have the Ultra Freeze Tag code. (I had lost it in a 
reformat, but someone sent it to me just recently. That was nice.) It 
has both MVDs and SSDs.

SSDs, IMO, are a bad idea for permanent inclusion, because small changes 
to the netcode necessitate changes in the SSD code, which is kind of 
hairy and scary. (Plus, it's very easy to forget.) MVDs, on the other 
hand, would be perfect. They're very general and frighteningly easy to 
implement. All you'd need is a restriction that the player taking the 
demo be a spectator.

If anyone wants to do MVDs, I'd be happy to supply a reference 
implementation. That should cut the work down considerably.
