You could modify it to use both Bio::Tools::Run::StandAloneBlast and  
Bio::Tools::Run::Infernal.  I'm still toying with the latter (only  
cmsearch works) but will probably get back to it this weekend as I  
have a ton of Infernal searches to do.

BTW, the latest Infernal (v0.72, which the wrapper supports) allows  
you to prerun a HMM before running with a full-blown CM search and  
allows you to specify a bit score cutoff to decrease the noise  
level.  Much faster, particularly when running full genome searches...
