Jim,
Amy and I addressed the issues of excess density, flat temperature profiles and large scale height about 10 years ago. Having flows of 30-40 km/sec, as is observed in TRACE and now verified by EIS, solves these problems quite nicely. So there is a viable mechanism other than nanoflares.

Dear Loops Friends,
If you are interested, the attached paper shows that coronal loops
cannot be explained by thermal nonequilibrium. The results appear to rule out the widespread existence of coronal heating that is both highly concentrated low in the corona and steady or quasi-steady (slowly varying or impulsive with a rapid cadence). Comments are welcomed.
Best wishes,
Jim
