21.
Plugin Framework<br />Available via nuget<br />Ships with the Player and WorldServer<br />Recommended way to write Plugins for VastPark<br />

22.
Portable IMML<br />Distribute a virtual world like a PDF!<br />Supports URI impersonation<br />Both single-user and multi-user scenarios are supported<br />Supports encryption<br />

23.
Widgets<br />A type of IMML container<br />Embeddable within other IMML contexts<br />

24.
Continuum<br />Continuum captures state changes<br />Binary file format<br />Supports forward and backwards playback and random seek<br />Designed to be streamed over a network<br />Supports arbitrary capture formats<br />ICodec<br />

OpenAvatar<br />

27.
LIXA<br />Supports groups of bones, allowing specific animations to play on specific bone groups independently.<br />Human readable layout, making it easy to copy and paste animation sequences from one file to another.<br />

28.
Metaforik<br />Entertains the idea of media as a concept<br />Supports for multiple representations of that concept<br />Permissions<br />Discovery<br />
