I thought I'd mention for posterity for folks searching the archive later:

For just the above, the tool "condor_findhost" is what you want to use 
in a ssh wrapper to find idle nodes that meet certain characteristics. 
See in the Condor Manual
   http://www.cs.wisc.edu/condor/manual/v7.2/condor_findhost.html

For adding in concurrency limits and queuing, probably doing something 
like what Ian suggested is best.  I.e., essentially submit a job that 
consists of an xterm or some such that pops open an interactive session 
w/ whatever concurrency limits required.
