I haven't had a chance to use them yet, but I'm quite interested in them.
I actually had a design in mind about six months before Xilinx announced
these LCA that was a perfect application for them.  Essentially, I wanted
to be able to configure the bulk of a machine's memory map on the fly,
in software, replacing what's currently a custom logic array device.  The
main problems with the LCAs (aside from haveing to use the IBM PC) was
their speed at the time and the cost.  Both of these factors are getting
in the right ballpark for my kinds of applications.  I'd really like to 
be able to program these things on a Sun or Apollo, though the support
may have to come from Xilinx; the last time I talked with them, they were
planning to be really protective of the internals of the device and how
its actually programmed.
