To answer your questions:

1. The code is source-encoded (closed source) and is not open source. I do not have any plans to release the code at this time.

2. It depends on what versions of vShare you are running. Essentially, the Mobility Mod for vShare is designed to integrate into vShare itself. It would replace the mobile TV link you posted above (HTML5). It would not, however, replace the WAP/xHTML version of your site. The mod is made for smart devices and not feature devices that rely upon WAP.

3. This depends on the vShare version. With 2.8.X, there is a single file that gets used for both vShare and the mobile site. The mobile video is converted, by default, into H.264 baseline single-pass at 640 x 480 x 30fps. It is never smaller than that by default, but can be changed very easily by the end-user. I have a few customers that have requested H.264 normal profile, single-pass at 1280 x 720 x 30fps.

The mod itself, does not support devices older than about 3 years due to the framework being used. The next version of the mod, which will be released later this year, will use a different framework, will still support devices from about 2009 and above, and will include an actual mobile player. Today, the mod does not use a player to play the videos.

As with anything I do, there is always opportunity to do something custom for you if the "out-of-the-box" solution doesn't work for you.

If you have any further questions, please let me know. It would be better to contact me through my site than the forums as I do not check it that often anymore. Thanks.
