>>From my (admittedly poor) understanding of regexes suggest that it is
going to be very long-winded. Basically, you have to look at only the
first five letters, exclude apostrophes, and see if there are at least two
adjacent consonants. I can't think of any other way than doing something
like:

 [[bcdfgjklmnprstvxz][bcdfgjklmnprstvxz]*]
  [[?][bcdfgjklmnprstvxz][bcdfgjklmnprstvxz]*]
  [[?][?][bcdfgjklmnprstvxz][bcdfgjklmnprstvxz]*]
  ...
  ]

This, of course, presupposes that you have already determined that the
string you are checking is a valid Lojban word.
