First story up is from swissinfo.org and contains this:
Pastoral assistants
Another sensitive issue due to be discussed was the role of lay theologians in the life of the Church.
In Switzerland, the shortage of priests has led to a greater dependency on non-ordained theologians to fulfil some priestly duties.
Two weeks ago the Swiss Bishops Conference issued a paper recognising this situation and officially permitting lay theologians to preach during Mass, in apparent contradiction of a Vatican edict of last year that only priests can deliver sermons.
The paper also gave lay pastoral assistants the right to baptise, and said Protestants could take communion in certain cases.
Now, as part of this prayer service, the lay leader is invited to offer some "reflections." The rite is careful to say that this must not be a homily, but it is, in fact, a homily by another name if the leader reflects on the readings.
It is a very simple step from allowing lay leaders to reflect on the readings in a prayer service, to allowing them to reflect on the readings at a Mass.
It would surprise me if the Vatican gave the Swiss bishops a particular dispensation for lay theologians to preach. If it did, I can think of a dozen other episcopal conferences which will immediately petition for the same dispensation. The US would be part of that 12.
