Inverse PCR

"Inverse PCR" is a method that should allow the amplification of the 
upstream and downstream regions flanking a DNA of known sequence. Briefly, 
the source DNA is circularized and PCR is carried out using primers in the 
opposite orientations to those normally employed for PCR. (Innis et al., 
PCR Protocols, A Guide to Methods and Applications, 1990).

My question is: Did anybody ever try this technique to complete cDNA's at 
                their 5'ends?
                Could this be an alternative to "RACE"?
