Hi, Dave:

yes, various collaborations like NFSNet continually work on a variety of NFS factoring challenges (Sam Wagstaff of Purdue U. maintains the NFS "most-wanted" lists). Every few years, their horsepower gets to the point where they try the next-larger RSA challenge number as a test for their latest algorithms and hardware. Peter Montgomery and Paul Leyland would be the guys to talk to about this, I believe.
