The student's experience of the LearnCube virtual classroom API (programmatically create a classroom URL) is the same as with a standalone virtual classroom (an unchanging URL).
It has the same key feature set:
Teachers and students can see and hear each other (live video streaming)
Students can ask questions and teacher can provide info/links (via the chat box)
Participants write and draw on the whiteboard at the same time (i.e. practice together)
The main difference is what your developers can do in the backend...
