Does ADI's Libiio support for a PCIe backend interface ?

Hello ,

Based on a document  "PlutoSDR.ppt", which describes following " LibIIO has an option of PCIe as the bacKend to connect to Remote Application",  Unfortunately I don't know whether ADI had supported this PCIE interface, or not on LibIIO.  I think the HighSpeed PCIe interface is very very useful for  " FPGA RF and  Powerful host CPU machine" use scenario. right ?

Does ADI's libiio have support PCIE interface , or not ?  Is there any schedule to immplement this ?  Thanks a lot ~
