Thanks Ian and Darshan for the explanations, That all makes sense,
By the way, Nobody will miss the variable/object syncing feature of
NowJS, at least I could not figure out how to use it effectively.
Without notification of when a variable is synchronized, it seems that
you would have to "poll" the memory for any difference "yuck."  IMHO
NowJS could drop that feature, and still be a great lib.

Okay now that I have looked at Bridge a little more, I see that
everything is a client, that is, "all application programming is done
in a Bridge client", of course these "clients" might act like a
servers...  So all the scaling concerns (that NowJS might run into)
can be centralized in the Bridge severs smarts, I imagine.

[my casual observation] Your Hello World example is just a little
convoluted (for a helloworld example), but I see how it is a simple
good "template for a service."
-- Thanks
