The routing or spanning tree solution is the most transparent to the

Yes. In fact, an explicit marker telling that there indeed was a proxy would be quite useful for SEND.
The concern here is that the explicit marker may need to be carried in all packets (not just ND packets) if there are asymmetric paths, or if paths can change dynamically after the initial ND exchange.

In other words, we need something like the experimental protocols
coming from the MANET wg (e.g., AODV, DSR, OLSR, TBRPF).
Even better would be a unified mechanism that combines the best
aspects of on-demand and reactive protocols.
Hmm.... I thought the idea of ND proxies was to avoid a complicated L3 device. If we need something like a routing protocol, maybe its time to pull out the proxy thing and replace it with a real L3 device?
I did not say "L3 device", nor did I intend to imply such. While some of the protocols I was referring to include extensions for passing around L3 prefix information, their primary function is to establish host routes based on information learned from neighbors, and this can happen based on either L3 addresses or L2 addresses as node IDs. In fact, the correct target domain of application in this context would seem to be as a replacement for the IEEE 802.1D spanning tree, so L2 addressing would seem to be indicated.
