I've been thinking (for another context, admitedly) about transfer of "goods, titles and remes"[1] focussing on the initiation of the transfer being focused on either the giver or receiver[2] on both voluntary and involuntary grounds[3]. Maybe I should add a third-party initiator, too in my musings. And maybe "exchange" can also apply here (though not in my original construct, save as a paired set of transactions, with similar overall flexibility).
I like the flexibility you already have in your DF-tailored ideas. Just posing my own pre-existing thoughts in case they are also of some conceptual use.
[1] Goods: Things that are items, destroyable, damagable, enhancable and used as components, but have a definite single existence; Titles (as in 'deeds', though might include positional 'titles' insofar as holding of rights/responsibilities) that are more nominal and could be split/overlapped by sufficiently pursuasive competing claims (but any one individual recognises just one possessor, whether they strictly agree with anyone else or not); "Remes" is my current catch all term for trivially/necessarily duplicatable 'stuff' (like genes and memes, but with the root of "reality", existence) that actually covers everything from knowledge/beliefs through to diseases, so maybe I need to split/offshoot memes again, but they all share so many of the same key qualities, like mutability.
[2] Some things are givable or takable, depending on circumstance, but something desired (greater wanting pressures than having, e.g. loot/vital knowledge) might be more taken/received, whereas others (greater having pressures than those for obtaining, e.g. a disease/credo) might be given/inflicted. With a chance success (or the complimentary chance of foiling) applicable to all. Did you find those pocketed gems? Were you convinced of an argument? Did they infect you? Could you properly understand the directions you asked for?
[3] A teacher with a willing pupil is different from a preacher with one they wish to convert. Palming a precious relic from an accomplice, to confuse the guards now stirred up like a hornet's nest, is a different thing from that item being planted upon you, unwittingly.
