Aye, just poking your model to make sure it's still cheddar and not
swiss. ;)
I still want to pass the whole object. I have just reread Shawn's
posting on the attribute flags within the DB subsystem. I think this
may be a good solution to resolving some unnecessary C&C failures
(those where different attributes have changed). I have to chew on
this awhile though.

Hmm, could even be a 8-bit wrapping counter on each attribute/method
forming a object signature string of sorts.

In all my previous postings, I have been coming from a DB viewpoint.
I am currently doing the language/VM design, so this current batch
of rethinking comes from that view point. I really must go back and
reread the watcher/spoof threads. In your diagram Object Y in
particular interests me (and probably GooGoo too). Do you have plans
to have an "in language" construct to explicit define Object Y as
a watcher of Object X?

GooGoo has interest in an explicit object(s) state. Yet rooms/others
only have interest in contacting objects. How to define within a mud
language? Or do all objects have this implicit ability? Or are
objects only interested if they provide a particular method to listen?
Once again I suspect we've had this discussion before and my synapses
have reconfigured. Why can't my mental search engine be more like

The neighborhood thread was mostly way over my head. It has lead to
strange thoughts of lists of points within simple circles along with
LOS detection between the center and outlying points.

Circuitry design eh?
In my language/VM model:
1) Event = application consistent transaction as defined by the mudlib
coder.
2) Events are initiated whenever a event method is called. An event method
call is pushed onto the execution queue and control resumes to the next
statement within a given VM stack. Thus event method calls do not "block"
and never return.
4) Event methods may call any number of regular methods or event methods.
5) Native server methods exist of both types and the reverse is also true
The server provides interface usable by mudlib coder. 'class character
implements user { bleh }' (BTW thank you Java for this useful concept)
