Great library. I did have a problem sending small blocks, which seems to be caused by sending a zero length transform to TransformBlock in RecordLayer.cs line 130. It was causing an exception, so I had to guard the call with:

if ( size - messTrailer != 0 )

not sure if that is the right fix, but things worked after that.

Thanks for an excellent (so far) library!

It should be fixed now.
