Thanks. So are we okay w/ one of the following option? (trying to understand the need here properly before I relay it internally). Options: (1) Provide EUD library and tools - proprietary w/o any login requirement. (2) Provide open-source EUD library and tools w/o any login requirement. Is Option (1) fine to begin with or option 2 is must? -- ---Trilok Soni
