[Icecast] Icecast on my website

Sorry to say, you are misinformed about this.
We are the developers of the original HE-AAC Encoder, Orban Opticodec-PC, and now all the StreamS Encoders, including the first with xHE-AAC now. So we know a thing or two about this, as we have thousands of encoders in use globally.
IE does not support AAC ADTS ICY streaming directly. Edge sort of does.
Real time metadata can be displayed in a Flash Player configured for FLV and using the KH Version of Icecast with a requested FLV stream with onMetaData metadata.
Another problem with the Flash Player is it uses one of the most horrible quality AAC decoders, and like Firefox Windows, is a fixed-point decoder. Additional explanation about this is probably beyond the interest here.
Once again to be clear here, a standard Icecast server serves AAC using ADTS with HTTP/HTTPS and embedded metadata which IS NOT ID3.

No flash player can fetch the embedded metadata due to security restrictions concerning non-standard request headers which is required in order to get the embedded metadata. A patch for ice cast to allow this however is quite possible, perhaps a config directive that tells icecast not to wait for the specific request header and send the embedded metadata regardless of the icy-metadata header will be a nice option.
In JavaScript it should be quite possible though.
Also, as for “not all browsers support the icy http streaming protocol.”
Never had any troubles playing icecast streams in any browser, it really depend on the browsers audio encoding support rather then the “protocol” which is plain http/s.

Not all browsers support the ICY HTTP Streaming Protocol. For AAC, it requires ADTS support, which contrary to popular belief, IS NOT RAW. It is AAC frames in an audio transport stream, not video TS.
To play this requires specific support, and it also needs to know about the embedded metadata, which once again, contrary to popular belief, ICY metadata IS NOT ID3vX.
ICY MP3 streaming is similar, although becoming less and less relevant because of low efficiency MP3.
There are a number of Flash Players that can play ICY/FLV formatted streams within browsers, including metadata, but with Flash being the security nightmare that it has become, this is another problem for ICY compatibility.
