What type of data can I send via a NetStream?

I know I can attach audio and video to a NetStream. Apparently, I can also attach text messages although I haven't seen an example (if you know of one, please let me know). I also know that I can record a stream via Flash Media Server. I'm wondering what other types of data – if anything – else I can attach to a NetStream开发者_开发技巧 and record?

Thanks

you can send almost anything (depends on the recieving side) using NetStream.send()
