open intent and intent specific to audience (even single agent)
http://supernaturista.com/ for each product has two exchange proposals, both offer same product and request different amounst of MXN
- first relates to anyone
- second relates to 'members' (I have 1 year membership), similar to https://schema.org/ProgramMembership
We can also have offer and request specific to particular agent e.g. "For you I'll offer it as gratitude for your contributions to the commons" (an offer not available for everyone)
