In order to not have people getting me wrong here, I'm stating now in 
public:

1) I like the idea of having diversity optionally controlled by the 
application.

2) My vote for S2API is final.

It is final, because the S2API is mainly affecting 
include/linux/dvb/frontend.h to add user-API support for new standards. I 
prefer the user-API of S2API over the one of multiproto because of 1).

All the other things around multiproto are dvb-core/dvb_frontend internal.
They have no relation with the user-interface. This I understood during 
the BOF, the microconf and the numberless talks we had around LPC.

Manu, it would be extremely good to have your modifications of 
dvb-core/dvb_frontend within the 4 weeks schedule in order to have the 
maximum number of hardware supported by that time. If you do not have the 
time to do that right now, I'm sure people are willing to help.

However - we can always change dvb_frontend/dvb-core internals at any time 
without breaking the user-interface.

best regards,
Patrick.
