   See <http://www.openbugs.info/w/OpenVsWin> for differences between
Open- and WinBUGS.  Lots of people still use WinBUGS/R2WinBUGS on Linux,
via WINE ...  The BUGS ecosystem is a little more complicated than it
used to be (with the existence of OpenBUGS and JAGS in addition to
WinBUGS, and the addition of BRugs, R2OpenBUGS, rjags, R2jags 
interfaces to the R2WinBUGS interface).  I don't know of any systematic
comparisons, though.

  good luck,
