I would base64 encode before you POST if from the client, store it that way in a TextProerty, then base64 decode / decompress when received back at the client. If you want to store it as binary on GAE, then base64 decode it into a Blob. Here are some code snippets I pieced together using your code, and something similar I do using HttpService -- apologies in advance for not extensively proofing it. HTH.

private var _serviceHttp:HTTPService = new HTTPService;

private function postBytes():void {
    var xml:XML = value;
    var bytes:ByteArray = new ByteArray();
    bytes.writeObject(xml);
    bytes.position = 0;
    bytes.compress();
    var enc:Base64Encoder = new Base64Encoder();
    enc.encodeBytes(bytes, 0, bytes.length);
    var myObj:Object = new Object();
    myObj["bytes"] = enc.toString();
    // myObj["other_variables"] = your_other_varaibles;
    _serviceHttp.method = "POST";
    _serviceHttp.resultFormat = "flashvars";
    _serviceHttp.url = your_url_here;
    _serviceHttp.addEventListener(ResultEvent.RESULT, urlHandler);
    _serviceHttp.addEventListener(FaultEvent.FAULT, urlErrorHandler);
    _serviceHttp.send(myObj);
}
