I agree completely. Its really as much about (if not more) about 
creating useful structures for the management of the services as it is 
about having some standard interchange / registry mechanism.

Well, I'm a bit of a fanatic so YMMV :-)

The whole Pepys thing is created by hand - most days I do one or maybe 
two entries, using LTM notation (Ontopia's text-based syntax). Thinking 
time + typing time + fixing up references comes to about 1 - 1.5 hours 
for each entry. About a third of that is fixing up time and less than a 
third typing time. Eventually the pain will make me write some better 
tools than my current "just use emacs" approach. Merging means I can 
work on the map in chunks which makes for a much faster debug cycle, 
but introduces its own problems of references between modules. There is 
some tedium, but then when you whack the whole lot together it all 
becomes worth it.

Of course, I'm a fanatic. YMMV ;-)

Certainly - although there are probably any number of screwed up 
event-based systems that could be learnt from if the implementers are 
willing to talk about them. I'm thinking of thinks like international 
shipping systems and warehouse tracking systems which deal with lots of 
events on the input - I would wager (a small amount) that there must be 
some implementations which try to manage the events, rather than the
