HTML chat works cross devices and this video chat software still updates its html client very few months. It may not be perfect yet but I highly recommend it to you ; You can google it from internet:)
This might be late but I think you can try 123 Flash Chat Software.
Its recent upgrade has been focusing on HTML 5 chat and gaining recognition for customers and coders in this field.
The video chat software can be seamlessly integrated into any kind of CMS and and it is very user friendly.
Thank you, indeed it took some time.
