Hi BW,

In the old mode of OODT, it did this via a centralized RMI registry. In the new
(web grid and beyond) it doesn't. Web-grid Profile/Product server handlers
and nodes are REST end-points and clients must know of them ahead of time.
We found over time that there were never thousands or 10s of thousands of 
some untenable number of web grid nodes, so we felt that direct REST calls
would be fine.

Cheers,
Chris
