You are right. But RUgby was Inter-REBOL to now.

On your OTOH: Yes. The plugins are actually the handlers on top of hipe.
Consider Rugby itself a plugin. RebXR SE is just another.

I could see if I can make the checksumming optional in the config dialect.
The [*** and ***] are in the post variable, which is a string, as begin and
end-point markers. That should be no problem.
OTOH, I may develop the Rugby bridge on top of hipe. Just a different handler
ready to rock with the rest of the world. What would such a protocol look
like (I ask you as you live in the world that needs it). Surely HTTP based,
but then?

I agree. And then marshaling libs in java, perl and whatever. Rebol rules ;-)
