So to summarize the current state of the discussion:

There are concerns about the usage of XEdDSA, which could be solved by
either implementing the XEdDSA conversion function in a non-GPL way
(which could also then be used in Olm), or by using two seperate keys
instead of just one. Afaik Andys PR does not cover the later option
right now, but I guess that could be easily added.

Either way, are there any other points speaking against Andys PR? I have
the feeling, that XEdDSA is the only real blocker right now (again,
which can be solved).
