PHPライブラリは誰かの「twitter2mixivoice.php」もあったけど、

(1) PEAR依存 (2) 自前だと修正・拡張ができる

なんで、ライブラリも自前で。

■問題点 (1) mixiボイスのAPIがない →よって、無理矢理ログインしてHTMLパース以外方法なし

(2) クロスドメイン制限 →swfで直接通信が理想なんだけど、mixiもtwitterもクロスドメイン制限があるので断念 　サーバかまして処理する事に

■主なポイント (1) AMF通信 →高速かつFlexとオブジェクトの親和性が高いAMFを採用 　JSON、XML変換できるけど、今は必要なし 　てか、XMLって遅いし面倒だし通信においてメリットあるのか？といつも疑問に思う。

(2) データのマージ 　twitterはJSON、mixiはテキスト取得して日付ソートしながらデータマージ 　（超暫定で最低限のタイトルと日付だけ）

とりあえずデータ取得＆マージまで作ったので、あとはマルチ投稿の仕様考える。 ある程度まとったら機能毎にクラス化へ。

途中までのソース うーん、デザイン的にコードは別途コンポーネント作った方がいいなw swf側ソースは、色々ネタが多いので別途記事にする予定（？）
