namd2.7b1, tip4p, and dummies

Hi all,

I have heard it said that namd can simulate 4 site water (tip4p, eg), and
even read in gromacs formatted topology. But in the manual under the gromacs
heading, it is mentioned that dummy atoms are not supported.

Does this refer only to gromacs formatted inputs? ie, namd2.7b1 supports
dummy atoms, just not via gromacs inputs? And if this is the case, where
else might I find a parameter file, namd ready, of tip4p/2005 ?
