In terms of scalability and integration:

[admin]

-how is it scalable to accommodate a high volume of traffic?
- is the transcoding of video (FLV) in real-time or can this be batch processed?

Only real time with current version of vshare.

-can the different processes (registration, transcoding, video assets) be separated out and hosted on different servers?

- is the video gallery configurable to work with a remote content delivery network?

- can databases be accessed by our promotions platform for better integration with our system?

Not possible now, we plan to add multiple server support, but no ETA yet.

- what type of custom development support do they offer?

Only community support is provided with forum. For paid support, we have partnered with hostonnet.com, they provide sever setup, installation for vshare.
