So, I read yesterday that Intel is going to start introducing quad-core CPUs sometime late this
year, rather than 2007 as originally announced.

Two questions occur to me:

   o How can we best take advantage of the multiple CPU cores in Gnu Radio?
Being able to process larger bandwidths and "do stuff" with that bandwidth
      would seem to be a good goal.   Like implementing a CDMA/GSM/whatever
basestation RF processor all inside Gnu Radio, for example. [Me, I just want to
      be able to process radio astronomy data at higher bandwidths :-)].

   o Is it time to think about moving away from USB for USRP?  Perhaps to
      PCI-X 2.0, or PCI-Express?
