Hey Olivier, I actually was the one that did a lot the work in adding the BRI support to libpri/chan_dahdi. NT PTMP is very significantly different, in that you have to do much more from a TEI management perspective. Most people's needs that I saw were actually fulfilled in using either NT or TE PTP or TE PTMP, since they were interfacing with PBXs or using TE-PTMP trunks from the telephone network to provide voice trunks for Asterisk. Right now, I would not preclude the possibility that NT-PTMP support might be added, but I could not give you a concrete time at which it will be done, since it will probably require some significant internal changes in libpri. To answer your final question, for now, if you need NT-PTMP mode, you should use mISDN.
