RE: discrete neural models

From going through the proceedings of the recently held
INNC-Paris conference, one can easily notice the surge of interests
in neural networks of discrete input/output/states
(for example, P-ROM, i-PROM, DN/PDN, and Aleksander's PLN, etc.),
beyond a originally small group in the London area. I learned that 
people are seeking linkage between this approach and the more
conventional approach with continuous activation and weights
for all links, and comparing their performance.

It seems to me, although 
I could be wrong, that this approach is gaining momemtum now,
and, due to a number of interesting learning algorithms proposed recently,
is becoming a viable alternative to the 'classical' neural network models.
especially in learning and performing in discrete input/output domains.
Yet, there has been few discussions and publications in mainstream neural net
journals, especially in US.

What is your  view on this type of neural network models?

These models have been applied to a wide variety of example 
domains, for example,

XOR problem (Aleksander 1989, Sun 1990)
Variable bindings in rule based systems (Sun 1989, etc.)
Modeling biological neural nets (Sun et al 1989, etc)
control problems (Tayler & Gorse 1990. )
Vision problems (Aleksander et al 1989)
