Would a straightforward addressing model along the following lines fit 
the bill?:

         -----  wifi "adhoc1"  ------  wifi "adhoc2"  -----
        |Host1|---------------|Router|---------------|Host2|
         ----- LL1         LL2 ------ LL3        LL4  -----
               G1                                G4



        "adhoc1" and "adhoc2": 802.11 ESSIDs in "ad-hoc" mode.
                               Each is an IPv6 subnet.
        LL1...4: IPv6 link-local addresses.
                 Self-formed according to rfc2464.
        G1, G4:  IPv6 global addresses, for example
                 2001:db8::1/64 and 2001:db8::4/64.
                 Manually assigned, or pre-configured with SNMP
                 or according to stateless autoconf rfc4862.
