So I emailed Jamis to see if they were offering their Sputnik as a frameset only. They responded:
Yes, we do offer the sputnik as a frame set and the MSRP is $525.
Thanks for your interest in Jamis Bicycles.

It seems a tad steep to me, since the MSRP on the complete is $700, but then again it's pretty reasonable for a Reynolds 631 frame and an Easton EC70 fork.
