Must be difficult to cope with poor equipment and slow Internet and it is probably worse for a technology enthusiast like yourself to experience the apathy by your students who do not wish to know about computers.
May we all encourage you not to give up and to keep a positive outlook and always remember that everyone of us already went through poor equipment and slow Internet in the beginning.
If you experienced poor sound during the session, worry not, all has been recorded and you will be able to enjoy the recordings and hopefully share them with your learners.
Second Life is one of most popular 3 dimensional virtual environments. Some people spend time in virtual worlds for entertainment but many universities and also individual educators use it for teaching and learning. I teach English in Second Life and also train teachers in using it with their students.
The best way to find out what a 3D virtual world is, is to try it. You can download the software and use it for free. The only downside is that it needs a good computer and broadband. If you want to give it a try, let me know and I'll help.
Btw, some of the sessions in this conference will take place in Second Life.
Actually, I received a letter telling about an online conference on 12 and 13 November. Thus, I joined Virtual Round Table. I hope we can have mutual benefit for our students. I like to know your modern experiences in teaching.
