Indeed, what matters is that both side of the pipe use the same
protocol.

Abicollab has already a protocol for collaborative edition and I am not
sure it fits in the SXE protocol: Abicollab has its own way to handle
undo and collision due to internet lag.
http://www.gnomejournal.org/article/31/gocollab----peer-to-peer-document-collaboration

SXE is limited to editing XML and cannot be used for collaborative
edition of non-XML documents or for protocols that are not
collaborative edition of documents (e.g. the gtetrinet protocol, or
the openarena protocol).

Instead of registering particular MIME types, I would register
particular protocol. For example, the gtetrinet protocol or the
abicollab protocol. We may have different protocol for ODT
collaborative edition with different ways to resolve collision due
internet lag (locking, merge).

I don't understand your second point.
