There's been a plugin programming feature request by VVIPP vux to get a custom node pin that could also accept value/color/string/transforms which got resolved a while ago. As there were no further complaints about the way it got implemented in the API we now will commit us to the following changes:

• All pins are now based upon the rather abstract node pins implementing different data interfaces.
• You now can create an unspecific node input that just asks for different interfaces dynamically and by that can work with different types of data of the builtin pins.

[Input("X")]
  public INodeIn FX; // unspecific regarding the expected data

later on you then can ask for a handle on the data via:

FX.GetUpstreamInterface(out myData);

• test for specific data by asking if myData supports IValueData, IStringData, IColorData, IRawData

As a side node: Making all pins compatible might help users at times. All data can now flow over GetSlice (Node) and Switch (Node) nodes.

See "girlpower\VVVV Plugin API\VariantPins" for an example for a Switch that is connected to colors, strings, values and whatnot at the same time.
