Can be added as a plug in to the VBrowser [movie].

Deployment:

The The WS-VLAM is currently deployed on the rapid prototyping environment (DAS3 clusters). It is now being tested to become availale on PoC infrastructure. However, WS-VLAM system can also be deployed on any Grid (Globus) enabled system. The WS-VLAM client can run on any desktop where java 1.5 is installed
